Question

2. Name excretory organs in human body. What
does each one of them excrete?
(URGENT) ;)​

Answer 1

Excretory organs of humans are kidney, liver, large intestine, skin and lungs. Although kidney are the main organ of excretion.

Kidney- Reabsorb and regenerate bicarbonate from urine, and excrete hydrogen ions and fixed acids into urine.

Liver- Harmful substances are excreted into the blood. Bile by-products enter the intestine and ultimately leave the body in bowel movements. Blood by-products are filtered out by the kidneys and leave the body in the form of urine.

Large intestine-The remains of food are turned into solid waste for excretion.

Skin-Perspiration is done by skin . It is made up of nitrogenous wastes (urea), salts, and water.

Lungs-They remove carbon dioxide, a waste product from our body.
