Definition of nephron
: one of the functional units of the kidney that filters the blood, selectively reabsorbs substances (such as glucose, ions, and amino acids), and excretes nitrogenous waste (such as urea) and excess water and salts in the form of urine
Note:
A nephron is made up of a glomerulus, Bowman's capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, collecting tubule, and collecting duct.
- Each kidney contains 1.5 million filters for blood, called nephrons, which carry away waste products.
