Quiz-Kidney structure

Rapid Review

Humans have two fist sized kidneys located in the lower back on both sides of the spine.Kidneys filter the blood and remove the wastes and release them into ureter, a tube that carries wastes to urinary bladder.The bladder can hold a maximum of 600 ml urine.

IThe functional unit of kidney are known as nephrons.Each kidney has 1 million nephrons in it.Nephrons are microscopic tubules that are responsible for filtration,reabsoption and secretion.

Each kidney is composed of three sections — the outer cortex, the medulla, and the hollow inner pelvis where urine accumulates before it travels to ureter.Each nephron consists of five parts — the Bowman’s capsule, the proximal tubule, the loop of Henle, the distal tubule, and the collecting duct.
