GENERAL HISTOLOGY

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 outer part of the kidney is the cortex and the inner part is the medulla. Within the cortex are glomeruli and tubules.

Detailed explanation-3: -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-4: -It contains the renal corpuscles and the renal tubules except for parts of the loop of Henle which descend into the renal medulla. It also contains blood vessels and cortical collecting ducts.
