THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Each kidney contains about one million tiny units called nephrons. Each nephron is made up of a very small filter, called a glomerulus, which is attached to a tubule. As blood passes through the nephron, fluid and waste products are filtered out.

Detailed explanation-2: -Several studies have shown that total nephron (glomerular) number varies widely in normal human kidneys. Whereas the studies agree that average nephron number is approximately 900, 000 to 1 million per kidney, numbers for individual kidneys range from approximately 200, 000 to >2.5 million.

Detailed explanation-3: -Each kidney contains over a million functional units, called nephrons, in the parenchyma (cortex and medulla). A nephron has two parts: a renal corpuscle and a renal tubule.
