What are the functions of the excretory system?

Answer 1

Excretory System

1. The human excretory system's organs help the body get rid of nitrogenous waste.
2. The primary excretory organs are the kidney, ureter, urinary bladder, and urethra.
3. The kidneys filter the blood, and the filtrate is collected as urine.

The excretory system is involved in several vital functions, including:

1. The excretory system gets rid of noxious and nitrogenous wastes.
2. These nitrogenous waste products, as well as extra salt and water, are eliminated from the body by the excretory system.
3. During cellular respiration, as cells break down carbohydrates, they release water and carbon dioxide as waste.
4. The excretory system assists with blood pressure control.
5. In addition to preserving the body's fluid balance, the urinary system regulates the generation of red blood cells by releasing the hormone erythropoietin.
6. By secreting the enzyme renin, the urinary system also helps to maintain appropriate blood pressure.
7. The excretory system keeps our body's water balance in check.
8. The kidney regulates the amount of water in the urine, which aids in keeping the water balance.
9. Urine is moved from the kidneys to the bladder by the ureters.
10. Until it is convenient to release it from the body, the bladder retains the urine.
11. The excretory system manages the concentrations of a variety of substances in the blood.
