Blood consists of plasma, red blood cells, white blood cells, and platelets. It makes up 8% of body weight and the average adult has about 5 liters. There are 4 main blood groups - A, B, AB, and O - which are determined by the presence or absence of antigens on the surface of red blood cells. Blood serves many important functions such as supplying oxygen to tissues, waste removal, temperature regulation, and providing nutrients to cells.

Body fluids- CSF, Lymph and Blood
This document provides information about three main body fluids: blood, lymph, and cerebrospinal fluid (CSF). It describes in detail the composition and functions of blood, including the different blood cells, plasma constituents, coagulation process, and pH regulation. Blood delivers nutrients and oxygen to tissues while removing waste. The coagulation cascade involves platelet activation and two pathways - the tissue factor (extrinsic) pathway and contact activation (intrinsic) pathway - that ultimately result in fibrin formation and clotting. Lymph and CSF are also briefly mentioned.

Blood
Blood is a complex connective tissue composed of plasma and formed elements. Plasma makes up 55% of blood and contains water, proteins, glucose, and other nutrients. Formed elements include red blood cells, white blood cells, and platelets. Red blood cells transport oxygen and carbon dioxide throughout the body. White blood cells provide defense against pathogens. Platelets help with blood clotting to stop bleeding. Overall, blood performs vital functions like nutrient delivery, waste removal, temperature regulation, and defense against disease.
Blood GCSE
Red blood cells carry oxygen from the lungs to tissues throughout the body. They are adapted with a thick, thin shape to fit through capillaries, having a large surface area to absorb oxygen. Red blood cells lack a nucleus and organelles to make more room for hemoglobin, which is the protein that carries oxygen. White blood cells defend against diseases by ingesting bacteria and viruses and producing antibodies. Platelets allow blood to clot to stop bleeding and prevent bacteria from entering the body. Plasma is the straw-colored liquid component of blood that dissolves nutrients, waste products, hormones, antibodies and transports them between organs.
Human blood intro
Human blood consists of plasma, red blood cells, white blood cells, and platelets. Plasma is 92% water and contains proteins, minerals, glucose, and other substances. Red blood cells transport oxygen throughout the body while white blood cells help protect the body from infection. Platelets help the blood clot to stop bleeding from damaged blood vessels. Together, these components of blood help maintain homeostasis in the body.

The document summarizes key information about blood, including:
- Blood is composed of plasma and formed elements. Plasma is 91.5% water and contains proteins, electrolytes, nutrients, gases, and waste products. Formed elements include red blood cells, white blood cells, and platelets.
- Red blood cells contain hemoglobin and transport oxygen and carbon dioxide. White blood cells help combat pathogens and foreign substances. Platelets help form blood clots during hemostasis.
- Blood functions include respiration, nutrient and hormone transport, waste removal, pH regulation, temperature control, water balance, and protection from pathogens through white blood cell activity and hemostasis.
Notes red blood cells and hemoglobin
The document summarizes key aspects of red blood cells and hemoglobin. It states that red blood cells are biconcave disks that lack a nucleus and organelles to make room for hemoglobin. Hemoglobin is an iron-containing protein composed of globin and heme subunits that binds oxygen in the lungs and releases it in tissues by binding carbon dioxide. The kidneys and liver regulate red blood cell production through erythropoietin stimulation of the bone marrow.

Anemia is a reduction in red blood cells or hemoglobin. It results in less oxygen being carried through the bloodstream. Anemia can be classified based on red blood cell size as microcytic (small), normocytic (normal sized), or macrocytic (large). Microcytic anemias occur when red blood cell production is decreased, resulting in small red blood cells. Causes of microcytic anemia include iron deficiency, thalassemia, and anemia of chronic disease.
Body fluid
The document discusses body water and fluid balance. It states that total body water is distributed between muscle (50%), skin (20%), blood (10%), and other organs (20%). Body water serves essential functions like transporting nutrients, maintaining temperature and tissue form. Daily water intake and output is usually balanced at around 2300 ml. Factors like temperature, diet, and endocrine glands affect fluid balance. The body maintains either positive or negative fluid balance in different conditions. The document also describes the composition and functions of intracellular fluid, extracellular fluid, and transcellular fluid. Various indicators can be used to measure the volume of different body fluid compartments.

Oxygen insufficeincy and sensory deprivation
The document discusses oxygen insufficiency and sensory deprivation. It defines oxygen insufficiency as a condition where the body or a region is deprived of adequate oxygen supply. Causes include decreased hemoglobin, altitude, tissue oxygen extraction issues, and impaired ventilation. Symptoms include cyanosis, altered breathing, and fatigue. Nursing assessments focus on respiratory status and signs of hypoxia. Oxygen therapy is the primary treatment. Sensory deprivation occurs when a person experiences decreased meaningful stimuli and can affect physical, cognitive, and emotional functioning. At-risk groups include those with sensory impairments or in long-term care. Preventing deprivation involves promoting healthy sensory stimulation.
Sensory deprivation
This document provides information about sensory perception and alterations. It discusses how people normally receive sensory stimulation through sight, sound, touch, smell, and taste. When sensory function is altered, through deprivation, overload, or deficits, a person's ability to relate to their environment changes. The effects of sensory deprivation can include hallucinations and cognitive and emotional disturbances. Nursing care for patients experiencing sensory alterations includes thorough assessment of their perception abilities and risks, and providing an optimal level of meaningful stimulation.
Sense organs
The document discusses the five main human sense organs - eyes, nose, ears, tongue, and skin. It provides details on the structure and function of each organ, noting that eyes are for seeing, nose is for smelling, ears are for hearing, tongue is for tasting, and skin is for touch. The conclusion states that these sense organs allow us to perform vital functions and that without them, we could not live.
Ovarian cancer by dr.saleh bakar
Ovarian cancer is the most common cancer of the female reproductive system. Risk factors include family history of ovarian or breast cancer, genetic factors, older age, and increased number of menstrual cycles. Symptoms are often vague in early stages but may include abdominal bloating, pressure, and pelvic pain. Diagnosis involves pelvic exam, ultrasound, CT scan, and CA125 blood test. Treatment consists of surgery to stage the cancer and remove tumors, followed by chemotherapy.
Ulcerative colitis
Ulcerative colitis causes inflammation and ulcers in the lining of the rectum and colon. Common symptoms include bloody diarrhea, abdominal pain, fatigue, and weight loss. Tests used to diagnose include physical exam, medical history, blood tests, and stool samples. While the specific cause is unknown, genetic and environmental factors may play a role. Treatment often involves medications like mesalazine which reduce inflammation. The disease course varies depending on extent of involvement, with limited disease usually having a milder course.
Inflammatory Bowel Disease
Inflammatory bowel disease refers to ulcerative colitis and Crohn's disease, which cause chronic inflammation of the intestines. Ulcerative colitis affects only the large intestine and causes ulcers, bleeding, and diarrhea. Crohn's disease can impact any part of the digestive tract and causes patchy inflammation that may lead to complications like fistulas or strictures. Both conditions are characterized by periods of remission and relapse of symptoms. Their causes are unknown but involve genetic and environmental factors. Diagnosis involves medical history, physical exam, blood tests, endoscopy, and imaging.
Sense organs
The document summarizes the five basic human sense organs - eyes, ears, tongue, skin, and nose. It describes the main receptors in each sense organ and how they detect stimuli like light, sound, taste, touch, and smell and relay this information to the brain.

inflammatory bowel disease (Ulcerative colitis , crohn's disease)
Inflammatory bowel disease (IBD) includes two major types: Crohn's disease and ulcerative colitis. Crohn's disease can affect any part of the gastrointestinal tract and often involves the full thickness of the intestinal wall. Ulcerative colitis only involves the innermost layers of the colon and rectum. Both conditions result from an interaction between genetic, immune, environmental, and bacterial factors. Symptoms include diarrhea, abdominal pain, and weight loss. Treatment focuses on inducing remission through medications like aminosalicylates or surgery to remove the colon. Crohn's disease is characterized by "skip lesions" and strictures while ulcerative colitis causes inflammation and ulcers confined to the colon.

Blood and hematopoietic system
Blood is essential to life. Blood circulates through our body and delivers essential substances like oxygen and nutrients to the body’s cells. It also transports metabolic waste products away from those same cells. There is no substitute for blood. It cannot be made or manufactured. Generous blood donors are the only source of blood for patients in need of a blood transfusion.
Johny's A&P Blood structure and function
Blood is a transport fluid that carries nutrients, waste products, gases, and blood cells throughout the body. It is composed of plasma and formed elements. Plasma is 90% water and contains proteins, salts, and other dissolved substances. Formed elements include red blood cells, white blood cells, and platelets. Red blood cells contain hemoglobin and transport oxygen and carbon dioxide. Blood volume varies based on factors like age, sex, and body composition. Blood types are determined by antigens on red blood cells and the presence of corresponding antibodies.
RBC YR1..pptx introduction to red blood.
blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Technically, blood is a transport liquid pumped by the heart (or an equivalent structure) to all parts of the body, after which it is returned to the heart to repeat the process. Blood is both a tissue and a fluid. It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood a fluid. If blood flow ceases, death will occur within minutes because of the effects of an unfavourable environment on highly susceptible cells.
Blood Anatomy and Physiology
The cellular components of blood are erythrocytes (red blood cells, or RBCs), leukocytes (white blood cells, or WBCs), and thrombocytes (platelets). By volume, the RBCs constitute about 45% of whole blood, the plasma about 54.3%, and white blood cells about 0.7%. Platelets make up less than 1%.
Blood.ppt
The circulatory system transports blood throughout the body, which contains formed elements like red blood cells, white blood cells, and platelets suspended in plasma. Red blood cells contain hemoglobin and transport oxygen and carbon dioxide. White blood cells help protect the body from pathogens. The circulatory system, including the heart, blood vessels, and blood, work together to transport nutrients, gases, hormones, and waste products throughout the body.

The document discusses the composition and functions of blood. Blood consists of cells suspended in plasma. The three main cellular elements are red blood cells, white blood cells, and platelets. Red blood cells contain hemoglobin and transport oxygen and carbon dioxide. White blood cells provide immune functions. Platelets assist in blood clotting. The plasma is mostly water but contains dissolved proteins and electrolytes. Blood has key roles in transport, regulation, and defense.
The Blood
Blood is a connective tissue which consists of various nutrients and waste products and circulates all over the body and remove out the waste products from the body.
Red blood cells (RBCs).pptx
(1) Red blood cells (RBCs) transport oxygen and carbon dioxide throughout the body via hemoglobin.
(2) RBCs are biconcave disks that allow for flexibility and efficient gas exchange. Their normal size is 7.2 micrometers in diameter.
(3) RBCs lack a nucleus and organelles. They have a lifespan of around 120 days before being destroyed and recycled by the spleen and liver.

composition of blood
Blood is composed of plasma, red blood cells, white blood cells, and platelets. Plasma is 90% water and transports blood cells throughout the body. Red blood cells contain hemoglobin which binds oxygen and transports it to tissues while removing carbon dioxide. White blood cells help fight infection. Platelets help the blood clot. Blood is classified into different groups based on the presence of antigens on red blood cells. Hemoglobin levels determine if a person has anemia. Malaria attacks red blood cells while sickle cell trait provides resistance to the disease.
Constituents and fuction of blood
This document describes the composition and functions of blood. It discusses how blood is composed of both cellular components (formed elements) suspended in plasma. The major cellular elements are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets. Erythrocytes make up about 45% of blood volume and contain hemoglobin which transports oxygen and carbon dioxide. Plasma is the liquid portion of blood and contains proteins, nutrients, wastes, and other dissolved substances. Blood performs critical functions of transporting substances, regulating homeostasis, and protecting the body from infection and blood loss.

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.

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).
