Question

The major excretory organ of the human urinary system is the
A) gall bladder.
B) pancreas.
C) liver.
D) adrenal gland.
E) kidney.

Accepted Answer

The kidney is the major excretory organ of the human urinary system. It filters waste products and excess fluids from the blood to produce urine, which is then eliminated from the body through the urinary tract. The gall bladder stores bile, the pancreas secretes digestive enzymes and insulin, the liver detoxifies the blood and produces bile, and the adrenal gland secretes hormones like adrenaline and cortisol – none of which play a major role in excretion of waste from the body.
