THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The renal cortex is where the nephrons (blood-filtering units) begin. Each kidney has 1 million nephrons. The filtering unit of the nephron is the glomerulus, and the glomerulus is attached to a tubule which removes wastes and returns the needed substances to your body.

Detailed explanation-2: -The kidney has an outer rim (cortex) and an inner core (medulla). Each kidney contains approximately 500, 000 glomeruli, which are small balls of capillaries (diameter 0.1 mm) through which the blood is filtered. Glomeruli are present only in the cortex.

Detailed explanation-3: -The cortex provides a space for arterioles and venules from the renal artery and vein, as well as the glomerular capillaries, to perfuse the nephrons of the kidney. Erythropotein, a hormone necessary for the synthesis of new red blood cells, is also produced in the renal cortex.
