Male reproductive system
The male reproductive system produces and transports sperm and releases it into the female vagina. The testes produce sperm, which travel through the epididymis, ductus deferens, and urethra. These ducts receive fluids from accessory glands like the seminal vesicles and prostate to nourish and transport sperm. During ejaculation, semen containing sperm is expelled from the urethra by the penis into the vagina to fertilize an egg.
Female reproductive system
The female reproductive system has several key functions: producing eggs, transporting eggs to the uterus to be fertilized, nourishing a developing fetus during pregnancy, and giving birth. The ovaries produce eggs and are located on either side of the uterus. The fallopian tubes connect the ovaries to the uterus and help transport eggs. The uterus receives a fertilized egg and provides nourishment during pregnancy. The vagina serves as the birth canal and allows for sexual intercourse. The external genitalia include the vulva, clitoris, and openings of the urethra and vagina.
General anatomy of the male reproductive system
This document summarizes the anatomy and physiology of the male reproductive system. It describes the internal structures involved in sperm production and transport, including the testis, epididymis, and ductus deferens. It also outlines the organs that produce seminal fluid and their contributions to semen. Finally, it details the stages of the male sexual response cycle, from arousal to resolution, focusing on the physiological changes involved in erection, ejaculation, and orgasm.
Urinary dent
The urinary system functions to eliminate waste from the body and regulate water balance and electrolyte levels. It consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys contain millions of nephrons, which are the functional filtering units that form urine by selectively reabsorbing useful substances while filtering out waste. Urine is transported from the kidneys to the bladder via the ureters. The bladder stores urine until voiding through the urethra. As we age, urinary function progressively declines as the bladder shrinks and urinary retention becomes more common.

- The functions of the urinary system include excretion of waste, regulation of blood volume and pH, and conserving nutrients.
- The kidneys filter blood to produce urine, while the ureters, urinary bladder, and urethra are involved in storage and elimination of urine.
- Urine production involves balancing water and electrolyte levels in the blood through selective reabsorption and secretion processes along the nephron.
The urinary system
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter the blood and produce urine by removing waste and regulating fluid and electrolyte levels. The urine passes from the kidneys to the bladder through the ureters. The bladder stores urine until emptying through the urethra. The functional unit of the kidney is the nephron, which filters blood to form urine through glomerular filtration, reabsorption, and secretion. Together, these components work to maintain homeostasis by regulating fluid balance and removing waste from the body.
Human Urinary system: Anatomy and Physiology
The urinary system consists of the kidneys, ureters, bladder, and urethra. The kidneys filter the blood to remove wastes and produce urine. The kidneys contain millions of nephrons, which are the functional filtering units. Urine is formed in the nephrons through glomerular filtration, tubular reabsorption, and tubular secretion. Urine flows from the kidneys to the bladder via the ureters for storage and then exits the body through the urethra. The urinary system plays an important role in homeostasis by regulating fluid balance and removing waste.
Excretory system
The document describes the anatomy and functions of the human excretory system. It details the major components, including the kidneys, ureters, urinary bladder, and urethra. The kidneys are retroperitoneal and contain nephrons, which are the functional units that filter blood to form urine. The nephrons contain a glomerulus for blood filtration and tubules for reabsorption and secretion. The excretory system regulates fluid balance and volume, removes waste, and controls blood pressure and red blood cell production.
Urinary system
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter the blood to remove waste and produce about 1-2 liters of urine per day. Rapid weight loss can cause the kidneys to drop in position and kink the ureters, backing up urine and potentially damaging the kidneys. Urine is formed through glomerular filtration, tubular reabsorption, and tubular secretion in functional units of the kidneys called nephrons. The urinary bladder stores urine temporarily until urination, when it is passed through the urethra out of the body.
09 urinary system
The urinary system regulates blood composition and excretes waste through the kidneys, ureters, bladder and urethra. The kidneys filter blood to form urine and regulate electrolyte and fluid levels. Urine passes from the kidneys through the ureters to the bladder, where it is temporarily stored until urination. During urination, urine exits the body through the urethra under control of sphincter muscles. The urinary system helps maintain homeostasis by regulating water balance and removing toxins and wastes from the bloodstream.
Endocrine system
The endocrine system regulates bodily functions through hormone secretion. The major endocrine glands include the hypothalamus, pituitary gland, pineal gland, thyroid gland, thymus, adrenal gland, pancreas and gonads. Hormones are either water-soluble and act through cell surface receptors or lipid-soluble and act inside target cells. The hypothalamus controls the pituitary gland which regulates the thyroid, adrenals and gonads. The thyroid regulates metabolism through thyroid hormones. The parathyroid regulates calcium levels. The adrenals secrete cortisol to regulate stress response and aldosterone to regulate blood pressure and electrolytes.
The urinary system
The kidneys filter blood to produce urine and are located on either side of the spine in the posterior abdominal wall. Each kidney contains around 1-2 million functional filtering units called nephrons. The nephron filters blood in the glomerulus to form an initial filtrate. Most of the filtrate is reabsorbed back into the bloodstream, with only around 1% excreted as urine. Through selective reabsorption and secretion, the kidneys regulate water and electrolyte balance and remove nitrogenous wastes from the body.
Urinary system
The urinary system includes the kidneys, ureters, bladder, and urethra. The kidneys filter the blood to remove wastes and regulate fluid, electrolyte and acid-base balance. The kidneys contain nephrons that filter blood in the glomerulus and reabsorb nutrients in the tubules. The remaining fluid becomes urine and drains into the bladder via the ureters. When full, the bladder empties urine through the urethra and out of the body. The urinary system works to regulate blood volume and pressure, maintain electrolyte and acid-base balance, conserve nutrients, and remove wastes and toxins from the body.
Human Urinary System
The human urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to produce urine. Each kidney contains millions of nephrons, the functional units that filter blood. Nephrons are composed of a glomerulus for blood filtration and a tubule for urine production and transport. Urine travels from the nephrons through the ureters to the urinary bladder for storage, then exits through the urethra.
Urinary system of infants and children
The urinary tract includes the kidneys, ureters, bladder, and urethra. In children, the kidneys are lobed and have fewer nephrons than adults. The kidneys help regulate water, salt, and waste removal. The ureters are wider in children and the bladder holds less volume. Development of urinary control occurs between 5-6 months and 1 year of age. Common urinary symptoms in children include intoxication, dyspepsia, pain, and dysuria.
Urinary system
The urinary system consists of paired kidneys, ureters, a urinary bladder, and a urethra. The kidneys filter waste from the bloodstream and regulate water and electrolyte balance. Each kidney contains nephrons with a glomerulus and tubular sections that allow for filtration, reabsorption, and secretion of substances. Urine travels from the kidneys through ureters to the bladder, where it is stored until excretion through the urethra. Key functions include filtering toxins and wastes from the bloodstream and regulating water balance through antidiuretic hormone.

Urine travels from the kidneys through ureters to the bladder, where it is stored until excreted through the urethra. The kidneys contain nephrons, which filter blood and form urine, and consist of a glomerulus and tubules. Urine is produced through filtration, reabsorption, and secretion processes in the nephrons and collects in the renal pelvis before exiting through the ureters into the bladder.
Renal System Anatomy
The renal system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to produce urine. The ureters then transport urine from the kidneys to the urinary bladder, where it is stored. When full, the bladder empties through the urethra, which exits the body. The kidneys are bean-shaped organs located in the abdominal cavity that contain millions of nephrons to filter blood. The ureters are muscular tubes that carry urine from the kidneys to the bladder. The bladder is a hollow organ in the pelvis that expands as it fills with urine before emptying through the urethra.
HUMAN URINARY SYSTEM - Anatomy & Physiology
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to form urine. The urine travels from the kidneys down the ureters to the urinary bladder, where it is stored until urination.

Urinary system
The urinary system consists of two kidneys, two ureters, one urinary bladder, and one urethra. The kidneys filter the blood and produce urine by regulating ions, volume, pH, and producing hormones. Urine passes from the kidneys to the bladder via the ureters. The bladder stores urine which is then expelled through the urethra. The functional unit of the kidney is the nephron, which filters blood and reabsorbs needed substances while secreting waste for urine production.
Functions of the frogs body systems
The document summarizes the main body systems of frogs:
- The reproductive system allows frogs to produce offspring through external fertilization, with males releasing sperm onto eggs laid by females.
- The endocrine system secretes hormones to regulate processes like hibernation and reproduction.
- Other body systems discussed include the nervous, muscular, skeletal, circulatory, respiratory, excretory, integumentary and digestive systems, which perform similar functions to humans.
Sexual orientation
The document defines sexual orientation as an enduring pattern of emotional, romantic, and/or sexual attractions to men, women, or both sexes. It is traditionally defined as heterosexuality, homosexuality, and bisexuality, with asexuality as a possible fourth category. The document also states that most people experience little to no choice in their sexual orientation, and that efforts to change orientation are unlikely to be successful. Biological factors like genetics, prenatal hormone levels, and birth order may influence sexual orientation.
Kidney physiology
The kidney is composed of an outer cortex and inner medulla, and contains over 1 million functional filtration units called nephrons. Each nephron contains a renal corpuscle for blood filtration and a renal tubule for reabsorption and secretion. Urine is formed in 3 steps - filtration of blood into nephron filtrate, reabsorption of useful substances back into blood, and secretion of waste products into filtrate. Hormones like antidiuretic hormone regulate water and electrolyte balance by controlling reabsorption in the kidney tubules.
Digestive types of transport
The document discusses metabolism and the absorption of nutrients. It states that sugars are the major fuel for making ATP in cells, with excess being stored as glycogen or fat. Fats are used to make ATP, build myelin sheaths, and insulate organs. Proteins are rarely used for energy and are broken down into amino acids to make enzymes and structural proteins. It also describes the different types of transport involved in nutrient absorption, including passive transport mechanisms like diffusion and facilitated diffusion, as well as active transport which requires energy.

Excretory system
The excretory system collects and eliminates waste from the body through various organs including the kidneys, ureters, bladder and urethra. The kidneys filter waste from the blood to produce urine, which is stored in the bladder and then passed out of the body through the urethra. The excretory system works to maintain homeostasis by regulating fluid levels and removing toxins.
Urinary system

Urine and urinalysis
Urine is the body's liquid waste composed of water, salt urea and uric acid. Urine can be evaluated by its physical appearance (color, cloudiness, odor, clarity), also referred to as a macroscopic analysis. It can be also analyzed based on its chemical and molecular properties, including microscopic assessment.

Anatomy by Dr. Maqbool Jabbar.pptx
This document provides information about the urinary system and its components. It discusses the kidneys, which filter waste from the blood and produce urine. The urine travels from the kidneys down the ureters into the urinary bladder, where it is temporarily stored until exiting the body through the urethra. The kidneys have several important functions like regulating blood volume and pressure. The document also describes the location of the kidneys, nephrons as the filtering units, and composition of urine.
Presentation
The excretory system removes waste from the body through various organs. It includes the lungs, liver, skin, and urinary system. The kidneys filter blood and produce urine by a process involving filtration, reabsorption, and secretion in functional units called nephrons. Urine travels from the kidneys to the bladder via ureters, where it is stored until excretion through the urethra. The system helps maintain homeostasis by regulating water balance and removing metabolic waste.
Urinary System
The urinary system consists of the kidneys, ureters, bladder, and urethra. The kidneys filter waste from the blood to produce urine, which is stored in the bladder and expelled from the body through the urethra. The kidneys contain nephrons, which are the functional filtering units that produce urine in a three step process of filtration, reabsorption, and secretion. Urine production and composition are regulated by hormones like renin, angiotensin, aldosterone, and antidiuretic hormone.
urinary system- pptx.pptx
The urinary system consists of the kidneys, ureters, bladder, and urethra. The kidneys filter waste from the blood to produce urine, regulate electrolytes and acid-base balance, and control blood pressure. The nephron is the functional unit of the kidney that filters blood to form urine via glomerular filtration, reabsorption of nutrients, and secretion of wastes. Urine is transported from the kidneys to the bladder via the ureters for storage and later excretion through the urethra.

Respiratory system
The respiratory system has two main functions: to supply blood with oxygen and remove carbon dioxide. It has an upper respiratory tract that warms and filters air and a lower tract that includes the trachea and lungs. The lungs contain millions of alveoli that absorb oxygen and release carbon dioxide and have a sponge-like structure.
Cardiovascular system
The cardiovascular system consists of the heart and blood vessels. The heart, made of strong cardiac muscle, has four chambers and pumps blood through two circuits. Deoxygenated blood enters the right atrium, travels to the right ventricle and lungs, then the left atrium and ventricle before being pumped through arteries like the aorta to the body. Oxygen-depleted blood returns via veins like the vena cava to the heart.
Digestive system
The digestive system breaks down food physically and chemically and absorbs nutrients into the bloodstream. It consists of a long continuous digestive tract that food moves through, including the mouth, esophagus, stomach, small intestine, and large intestine. Accessory organs that produce fluids entering the digestive tract include the liver, which produces bile to help digest fat, the gallbladder which stores and concentrates bile, and the pancreas which produces digestive enzymes.
Muscles
Muscles are able to contract and shorten, pulling on bones via tendons to cause movement. They require a lot of oxygen and nutrients delivered by blood vessels. Muscle cells use aerobic respiration to generate energy from oxygen, and if worked too hard will switch to less efficient anaerobic respiration producing lactic acid. The document also lists some major muscle names in the arms, trunk, and legs.
Bones
The document lists and describes the bones that make up the axial skeleton and appendicular skeleton. The axial skeleton includes the skull, rib cage, and vertebrae. The skull has 22 bones including 8 in the cranium and 14 in the face. The rib cage contains 12 ribs pairs and the breastbone. The vertebrae consist of cervical, thoracic, lumbar, sacrum and coccyx bones. The appendicular skeleton attaches the arms and legs to the axial skeleton. It lists the bones of the arm as the clavicle, scapula, humerus, ulna, radius and carpals. The bones of the leg are the pelvis, femur, tibia, fibula,
Organ systems projects
The document provides instructions for creating an interactive notebook on human biology. Students are told to staple paper to the cover and include identifying information and a picture. The notebook then outlines and describes the 11 human organ systems, their functions, and key organs. Students will work in groups to write and perform a 1-2 minute skit about the location and function of an assigned organ.
Climate change poster
The document provides instructions for creating a poster showing the impacts of climate change on a specific area or species. It states that the poster should identify at least 3 impacts of climate change, providing a brief explanation and picture for each impact. It also lists potential topics that could be covered on the poster, such as the impacts of climate change on polar bears, coral reefs, agriculture, and coastal cities.
Invasive plants notes
The document defines invasive plants as non-native plants that spread rapidly, out-compete native plants, and have negative ecological or economic impacts. It lists traits of invasive plants such as fast growth, efficient nutrient and water absorption, both sexual and asexual reproduction, effective seed dispersal mechanisms, wide environmental tolerance, and some produce toxins that inhibit other plants. The document also notes invasive plants cost over $140 billion per year in the US, threaten half of endangered species, and can be toxic, increase fire hazards, or cause injury with spines.
Flower notes
Flowers are reproductive organs that bring together pollen and eggs to produce seeds. They have four main parts: sepals which protect the developing flower, petals which are often brightly colored to attract pollinators, stamens which are the male part containing anthers that produce pollen, and carpels which are the female part containing an ovary with eggs and a stigma to receive pollen. A flower lab involves making a detailed drawing of a flower, labeling the parts, and cutting open the ovary to locate the eggs inside.
Seed notes
Seeds contain an embryonic plant and stored food to nourish and protect the embryo. Seeds also disperse the embryo through mechanisms like wind, water, or animals. Additionally, seeds enter dormancy to wait for suitable environmental conditions before germinating. Seeds are important because many are edible and provide humans with most of their calories through cereal grains, beans, and nuts. Students are instructed to write a letter explaining what seeds are and why they are important from the perspective of a seed.
Leaf structure
The document summarizes the structure and function of leaves. It notes that leaves contain a cuticle, epidermis, palisade mesophyll, spongy mesophyll and vascular bundles. The cuticle forms a waxy outer covering that prevents water loss. The epidermis forms the top and bottom layers of the leaf and provides protection. The palisade mesophyll contains tightly packed cells with many chloroplasts and performs most photosynthesis. The spongy mesophyll contains loosely packed cells with fewer chloroplasts. The vascular bundles contain xylem and phloem that transport water and food. Stomata are pores on the underside of leaves that open and close to regulate gas exchange.
Photosynthesis
Photosynthesis is the process by which plants use sunlight, water and carbon dioxide from the air to produce sugar, which plants then use as food. It takes place in chloroplasts, small oval structures inside plant cells that contain chlorophyll to capture light energy. Chloroplasts were originally free-living bacteria that became incorporated into plant cells. Photosynthesis also produces oxygen as a byproduct.
Intro to plants
All plants share three main traits: they are eukaryotic, have cell walls containing cellulose, and produce their own food through photosynthesis. The document discusses four types of plants: mosses, ferns, gymnosperms which have cones, and angiosperms which have flowers.
Classification notes
Students are instructed to prepare their interactive notes for a taxonomy unit by making a cover page with their name, class, and an illustration of taxonomy. They should staple paper behind the cover to take notes on classification, where organisms are now grouped by evolutionary relationships determined by characteristics and DNA sequencing. The taxonomic categories from domain to species are listed, with an example classification of humans provided. Students are tasked with creating a mnemonic and drawing to illustrate the categories for their interactive notes.
Cladograms
A cladogram is a diagram that shows the evolutionary relationships between species by depicting lineages and their shared common ancestors. It represents groups of species that share a single common ancestor as clades. Derived characteristics are traits that evolved in a common ancestor and were passed down to its descendants, helping to determine how species are related on the cladogram. The example shows how to build a cladogram by determining which species share certain traits like legs, fur, being carnivorous, or having retractable claws.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
Novas diretrizes da OMS para os cuidados perinatais de mais qualidade
Novas diretrizes da OMS para os cuidados perinatais de mais qualidadeProf. Marcus Renato de Carvalho
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

ABDOMINAL TRAUMA in pediatrics part one.
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.
