The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in the kidney. The filtrated blood is carried away from the kidneys by the renal vein (or kidney vein).

What are the excretory substances?
Excretion is the physiological process of elimination of metabolic waste from the body. The excretory products include amino acids, urea, uric acid, carbon dioxide, water, and ammonia.
What are the 3 substances that the excretory system removes from the body?
What are three substances that the excretory system removes from the body? The kidneys remove the nitrogenous wastes such as urea from the blood, and salts and excess water are also removed from the blood and excreted in the form of urine.
What substances does the excretory system get rid of waste?
This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.
What is the main excretory substance in humans?
Urea and carbon dioxide is the main excretory product in humans.
What are the 4 main body parts in the excretory system?
Organs of excretion make up the excretory system. They include the kidneys, large intestine, liver, skin, and lungs. The kidneys filter blood and form urine. They are part of the urinary system, which also includes the ureters, bladder, and urethra.
What are the 4 functions of the excretory system?
The important functions performed by the excretory system include- elimination of wastes, eliminate waste byproducts excreted by the cells, prevent the accumulation of harmful chemicals in the body, and maintain a balanced chemical concentration in the body.
What are the main functions of the excretory system?
The function of the excretory system to remove wastes from the body. These wastes include water, CO2, nitrogen, salts, and heat. Metabolism: The process of the body coverting food into energy. As a result of metabolism, there are waste products.
Which substances are produced as waste products by plants?
Plants. Plants need to excrete excess carbon dioxide and oxygen. Carbon dioxide is a waste product of aerobic respiration in plant cells. Oxygen is a waste product of photosynthesis .
What is the major organ of the excretory system?
Kidneys. The paired kidneys are often considered the main organs of excretion. The primary function of the kidneys is the elimination of excess water and wastes from the bloodstream by the production of the liquid waste known as urine .
Which are the major excretory products in plants?
Carbon dioxide, excess water produced during respiration and nitrogenous compounds produced during protein metabolism are the major excretory products in plants. Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration.
What does the excretory system remove?
Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Organs of excretion make up the excretory system. They include the kidneys, large intestine, liver, skin, and lungs.
Which of the following substance is not an excretory product in mammals?
Faeces is discharged through the anus or cloaca which is not a part of the excretory organs in mammals.
What are the three main excretory products?
The major excretory products are carbon dioxide, excess water, and nitrogenous compounds like ammonia, urea, uric acid, etc. Carbon dioxide and water are produced in the process of tissue respiration.
What are the main products of excretion?
Materials eliminated via the kidney include nitrogenous waste products (ammonia, uric acid, urea, creatine, creatinine, and amino acids), excess quantities of salts and water that may be taken into the body, and various other organic materials produced by life-sustaining chemical reactions.
What is the excretory product of the skin?
Skin. Sweat glands in the skin produce sweat. The water in sweat helps to keep the body cool in hot conditions, and it contains salts and urea .
