Name the part performing Excretion.

Solution

Part performing excretion is Glomerulus.
The main function of the kidney is the excretion of body wastes and harmful chemicals into the urine. Each kidney contains about one million nephrons. The nephron has three primary regions that function in the renal excretion process: the glomerulus, proximal tubule, and the distal tubule. Filtration takes place in the glomerulus, which is the vascular beginning of the nephron.
