Question

Explain the structure and functioning of structural and functional unit of kidney.​

Answer 1

Answer:

Structure:

-Nephrons are the microscopic structural and functional unit of the kidney. Nephrons are composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and an encompassing Bowman's capsule.

-Its chief function is to regulate water and soluble substances by filtering the blood, reabsorbing what is needed and excreting the rest as urine.
