The main excretory system in humans is the urinary system. The skin also acts as an organ of excretion by removing water and small amounts of urea and salts (as sweat).


The urinary system includes a pair of bean-shaped kidneys located in the back of the abdominal cavity. They remove urea, toxins, medications, and excess ions and form urine. The kidneys also balance water and salts as well as acids and bases. At the same time, they return needed substances to the blood.


What is the main excretory system in humans____________________

What is another organ of excretion? ___________________________


Each kidney contains over one million nephrons, each of which consists of a tuft of capillaries surrounded by a capsule on top of a curving tube. The tuft of capillaries is called a glomerulus. Its capsule is cup-shaped and is known as Bowman's capsule. The glomerulus and Bowman's capsule form the top of a tube, the renal tubule. Blood vessels surround the renal tubule, and urine forms in it. The renal tubules of many nephrons join in collecting tubules, which in turn merge into larger tubes and empty their urine into the ureters in the renal sinus.
