The excretory system removes waste from the body through urine and feces. It includes the kidneys, which filter waste from the blood to produce urine, and the ureters, urinary bladder, and urethra, which transport urine from the kidneys out of the body. The kidneys contain nephrons that filter waste in stages, removing wastes while retaining needed materials in the blood. Once food is digested, waste enters the excretory system from the digestive system and is eventually eliminated from the body.

Functioning Organisms - 05 The Excretory System
The excretory system is responsible for processing and eliminating metabolic waste from the body. Carbon dioxide is removed through exhalation via the lungs. The kidneys filter blood in the nephrons, removing urea and salts to produce urine, which is stored in the bladder and then excreted. Other organs such as the skin, liver, and intestines also play roles in excretion, with the skin releasing wastes in sweat and the liver breaking down toxins and urea. Together, these organs comprise the excretory system and ensure harmful metabolic byproducts are continuously removed from the body.
Excretory system
The excretory system removes waste from the body through excretion. The kidneys are key excretory organs that filter waste like carbon dioxide, water, and nitrogenous waste from the blood to produce urine. The urine passes from the kidneys through ureters to the urinary bladder, where it is temporarily stored before leaving the body through the urethra. The nephrons are the functional units of the kidneys that filter the blood and produce urine, consisting of a glomerulus surrounded by Bowman's capsule and tubules.
Human Excretory System (lungs, kidney)
The lungs in the respiratory system excrete some waste products, such as carbon dioxide and water.
The skin is another excretory organ that rids the body of wastes through the sweat glands.
The liver (via the intestines) excretes bile pigments that result from the destruction of hemoglobin. It also converts nitrogenous waste from the break down of proteins into urea.
The major task of excretion still belongs to the kidneys, the major organ in the urinary system. If it fails the other organs cannot take over and compensate adequately.

Form 3 PMR Science Chapter 3 Excretory System
The kidneys filter waste from the blood and regulate water and electrolyte balance. They remove urea, uric acid, and creatinine. The kidneys are supplied by blood from the renal arteries and drain into the ureters. They filter minerals, sugars, amino acids and waste from the blood and reabsorb useful substances while excreting waste like urea in the urine. Kidney failure requires dialysis or transplant to filter the blood.
Excretory System
The excretory system, mainly the urinary system, works to eliminate waste from the body through urine. The hypothalamus monitors fluid levels and sends hormones to regulate fluid balance by controlling how much water the kidneys return to the bloodstream or remove as urine. The kidneys filter blood, reabsorbing useful nutrients while collecting waste in urine. Urine travels from the kidneys through ureters to the bladder and is then expelled through the urethra. Diseases can occur if the kidneys fail to remove waste or if infections block the urinary tract.

Excretory system
This document discusses several components of animal excretory systems:
1. The excretory system regulates chemical composition of body fluids by removing waste and maintaining proper water, salt, and nutrient levels.
2. Osmoregulation controls water balance in aquatic, terrestrial, and hyperosmotic environments using different processes depending on the animal. Aquatic animals regulate to match surrounding water, while terrestrial animals conserve water through impermeable surfaces and kidneys.
3. Kidneys filter blood, reabsorb useful molecules, and excrete waste as urine, regulating water, waste, and pH balance.

Excretory system presentation
The urinary system filters waste from the blood in the kidneys, which contain nephrons that act as tiny filters. The kidneys remove waste through the ureters into the urinary bladder, where urine is stored until expelled through the urethra. Each kidney contains approximately one million nephrons that filter wastes like urea and salt from the blood into collecting tubes and eventually the bladder.
Excretory System
The excretory system regulates homeostasis by removing metabolic, liquid, and gaseous waste from the body. The kidneys filter blood and produce urine by removing wastes and excess water. Urine contains urea, uric acid, ammonia, hormones, dead blood cells, proteins, salts, and toxins. The kidneys filter blood through nephrons, which collect the filtrate and modify it into urine by selectively reabsorbing necessary substances and secreting others. Urine is stored in the bladder and expelled through the urethra.

The excretory system removes waste from the body through various organs like the skin, liver, lungs, large intestine and kidneys. The objectives of the presentation are to define the excretory system, describe the anatomy and physiology of excretory organs like the kidneys and nephrons, and explain the functions of the kidneys and other parts of the urinary tract.
The urinary system
The urinary system consists of two kidneys, two ureters, a bladder, a urethra, and sphincter muscles. The kidneys filter waste from the bloodstream and produce urine, which travels through the ureters into the bladder. The bladder stores urine until it is full, at which point the sphincter muscles relax and allow urine to pass through the urethra to be released from the body. Together these organs work to regulate waste removal, fluid balance, and blood pressure.
Urinary system project p.p.
The urinary system removes waste from the body through the kidneys, ureters, bladder, and urethra. The kidneys filter waste from the blood to produce urine, which travels through the ureters to the bladder. The bladder stores urine until it is released through the urethra. The urinary system works with other body systems like the circulatory, nervous, and muscular systems to effectively regulate fluids and expel waste from the body.
Excretory system
The excretory system works to maintain balance in the body by filtering waste and toxins from the blood and eliminating them from the body. It is led by the kidneys, which filter waste through tiny nephrons. The kidneys then produce urine, which travels through ureters to the bladder for storage and is later released through the urethra. In addition to the kidneys, the large intestine, liver, skin, and lungs all play roles in excretion to eliminate various waste products.
Stem 12 excretory
The excretory system removes waste from the body through various organs like the lungs, liver, skin, and urinary system. The lungs release carbon dioxide and water, the liver removes urea, the skin secretes sweat containing water, salts, and urea, and the urinary system filters blood in the kidneys and removes urine containing water, salts, and urea through the ureters, bladder, and urethra. Common diseases include kidney stones from dietary and infection causes, urinary tract infections from bacteria, and bladder cancer which can result from smoking or chemical exposure.
The urinary system
The urinary system consists of the kidneys, ureters, bladder, urethra, and sphincter muscles. The kidneys filter waste from the bloodstream and produce urine. The ureters carry urine from the kidneys to the bladder, which stores urine until urination. During urination, signals cause the bladder to contract and the sphincter muscles to relax, releasing urine through the urethra. The typical adult produces around 1.5 quarts of urine per day to remove waste from the body.
Excretory and urinary systems
The excretory system removes waste from the body through organs like the kidneys, ureters, bladder, and urethra. The kidneys filter blood and remove wastes, which travel through the ureters to the bladder. The bladder stores urine until it is released through the urethra. The urinary system is part of the excretory system and keeps the body balanced by filtering wastes from the blood and removing excess water and salt.
Excretory System
The process of excretion involves the lungs, kidneys, and skin removing waste from the body. The urinary system, including the kidneys, ureters, bladder, and urethra, filters liquid waste from the blood to produce urine, which is stored in the bladder and expelled through urination. The kidneys filter blood multiple times per day to remove waste and produce urine for excretion.
excretory organs
The excretory system removes waste from the body through various organs to maintain chemical homeostasis. The main organs are the liver, kidneys, lungs, and skin. The liver breaks down toxins and produces bile to break down fats. The kidneys filter blood to remove urea and other wastes to produce urine. The lungs diffuse carbon dioxide out of the bloodstream during respiration. The skin excretes sweat in mammals and urea and carbon dioxide in amphibians.

Human excretory system
The excretory system consists of four main organs that remove waste from the body: the skin, kidneys, ureters, and bladder. The kidneys contain millions of nephrons that filter waste from the blood and produce urine. The ureters carry urine from the kidneys to the bladder, where it is stored until release through the urethra. Together, these organs maintain homeostasis by excreting wastes and regulating fluid levels in the body.
CMP3202_P-B_PROJECT_(1)[1].pptx
The human excretory system maintains homeostasis by removing metabolic waste from the body. The major organs involved are the kidneys, which filter blood to remove waste that is excreted in urine, and the bladder, which stores urine until excretion through the urethra. The functional unit of the kidney is the nephron, which contains a glomerulus that filters blood and tubules that reabsorb useful substances and remove waste to form urine. Together, these organs work to eliminate toxins from the bloodstream and regulate fluid balance in the body.
LIFE PROCESSES PART- 7.pptx
The document discusses excretion in human beings. It describes how the kidneys, ureters, urinary bladder, and urethra make up the human excretory system. The kidneys filter waste products from the blood to produce urine, which is stored in the bladder and released through the urethra. The basic filtration unit in the kidneys is called a nephron, which filters the blood and selectively reabsorbs useful substances before urine is produced.

Excretory system
- 1. The Excretory System By: Andrew Perdock, Chase Witherspoon, Josh Isenhour, and Nabil Ranjbar
- 2. What It Is The excretory system is the system in the body that collects wastes produced by cells and removes the wastes from the body. The removal process is known as excretion.
- 3. What It Does The excretory system eliminates wastes from the body (pee and poop).
- 4. Where It Happens Hopefully, you know how to eliminate wastes in the toilet and not in a diaper. But seriously, when you eat food and the chemicals of the food break down, that is called the digestive system. Food eventually ends up in the excretory system. Once it is in the excretory system, wastes are eventually eliminated.
- 5. How It Happens The structures of the excretory system that eliminate urea, water, and other wastes include the kidneys, ureters, urinary bladder, and urethra. The two kidneys are the major organs of the excretory system. Two wastes that your body must eliminate are excess water and urea. The wastes are eliminated in urine, a watery fluid that contains the urea and other wastes. Urea is a chemical that comes from the breakdown of proteins. Urine flows from the kidneys through two narrow tubes called ureters. The ureters carry the urine to the urinary bladder, a sacklike muscular organ that store urine. Urine flows from the body through a small tube called the urethra. Each kidney contains about a million nephrons. Nephrons are tiny structures that remove wastes from blood and produce urine. The nephrons filter wastes in stages. First, both wastes and needed materials,
