Kidney. In humans, the kidneys are two reddish-brown bean-shaped blood-filtering organs [ 1] that are a multilobar, multipapillary form of mammalian kidneys, usually without signs of external lobulation. [ 2][ 3] They are located on the left and right in the retroperitoneal space, and in adult humans are about 12 centimetres ( 41⁄2 inches) in ...
Not to be confused with Human kidney. The kidneys are a pair of organs of the excretory system in vertebrates, which maintain the balance of water and electrolytes in the body ( osmoregulation ), filter the blood, remove metabolic waste products, and, in many vertebrates, also produce hormones (in particular, renin) and maintain blood pressure ...

The typical mammalian kidney consists of a renal capsule, a peripheral cortex, an internal medulla, one or more renal calyces, and a renal pelvis.
Renal physiology. This illustration demonstrates the normal kidney physiology, including the Proximal Convoluted Tubule (PCT), Loop of Henle, and Distal Convoluted Tubule (DCT). It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology ( Latin rēnēs, "kidneys") is the study of the physiology ...

The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the ...
The nephron is the minute or microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman's capsule. The renal tubule extends from the capsule.
