The excretory system removes waste from the body through various organs. It maintains homeostasis by filtering out metabolic waste like carbon dioxide, urea, and salts through the lungs, liver, skin, and urinary system. The kidneys filter blood to form urine via nephrons. Urine is transported by the ureters to the bladder and then exits through the urethra. Common diseases include kidney stones, urinary tract infections, athlete's foot, and bladder cancer.
The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.

Excretory system and its parts with detailsরেজা তানজিল
this is a group presentation about the excretory system
The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body.
The urinary system's function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra. The body takes nutrients from food and converts them to energy.
Life of every organism depends on certain basic processes. Excretion is one among them. Different organisms follow different modes of excretion. In complex organisms including humans, there is a specialized system for excretion called human excretory system.

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.

Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...Oleg Kshivets
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).
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
2. The Excretory System
is a passive biological system that
removes excess, unnecessary materials
from an organism.
Excretion is the removal of metabolic
wastes from the body, including toxic
chemicals, excess water, carbon dioxide
and salts.
3. Functions:
1. Metabolic and toxic wastes removal
2. Collect water and filter body fluids
3. Helps maintain Homeostasis (stable
internal state of the body)
4. Eradicates harmful chemical build-
ups
4. Metabolic Wastes
Waste A by product of :
carbon dioxide Cellular respiration
salts Neutralization
urea Protein metabolism,
Deamination
water Dehydration
synthesis and
respiration
6. Lungs
A pair of cone-shaped, porous and
spongy, located in the chest that are
composed of bronchioles, alveoli,
blood vessels, lymphatic, nerves and
elastic connective tissues.
As an excretory organ, it releases
carbon dioxide and some water vapor
as a waste product through
respiration.
8. Liver
Function is for deamination
A process by which some
proteins & other nitrogenous
compounds are broken down
in the liver.
As a result, urea is formed.
10. Skin

which is a mixture
of three metabolic
wastes: water, salts,
& urea through the
sweat glands.
Two types:
-Eccrine
-Apocrine
11. Urinary System
A group of organs in the body
concerned with filtering out excess
fluid and other substances from the
bloodstream.
Urination or Micturition is the act by
which urine (combination of salt,
water, and urea), is expelled from the
urinary bladder

nephrons
- The filtering layer
Renal Medulla
- Middle layer
- The Collecting layer
- Contains the Renal Pyramids
Renal Pelvis
- Center of the kidney
- The Draining Layer

17. Nephrons
The basic structural and functional unit of the
kidney
Comes from the Greek word (nephros)
meaning kidney.
A long tubule with a series of associated
blood vessels
Chief function is to regulate water and soluble
substances
Each kidney has more than 1,000,000 of
them
Each nephron is made of a cup shaped
portion called Bowman’s capsule, tubules
and a network of capillaries.
19. How is urine formed ?
Three major processes are involved in the
formation of urine:
filtration -filters the blood to produce a
filtrate
reabsorption - selectively reabsorbs
needed water and essential solutes from
the filtrate
secretion - moves substances into the
filtrate for removal as part of the urine
20. Ureters
Two tubes that drain urine from
the kidneys to the bladder
Each is a muscular tube about
10 inches (25 cm) in length and
3mm in diameter.
21. Urinary Bladder
The urinary bladder is the
organ that collects urine
excreted by the kidneys prior to
disposal by urination.
It is a hollow muscular, and
distensible (or elastic) organ,
and sits on the pelvic floor.
can hold approximately 17 to
18 ounces (500 to 530 ml) of
urine.
22. Urethra
A tube which connects the
urinary bladder to the outside
of the body
The function of the urethra is to
remove urine from the body
through urination
It measures about 1.5 inches
(3.8 cm) in a woman but up to
8 inches (20 cm) in a man.
The urethral sphincter is a
collective name for the muscles
used to control the flow of urine
from the urinary bladder.
