PATHOLOGY

Detailed explanation-1: -The renal cortex has a more grainy texture, while the medulla is smoother. Both sections contain tubules (small tubes), but the cortex has the glomeruli (filters) and convoluted (twisted, curvy) tubules and blood vessels which gives it a grainy appearance.

Detailed explanation-2: -All glomeruli are located in the cortex, while tubules are located in both the cortex and the medulla. The urine drains from the collecting ducts of many thousands of nephrons into a cuplike structure (calix). Each kidney has several calices, all of which drain into a single central chamber (renal pelvis).

Detailed explanation-3: -The kidney is covered by a connective tissue capsule. 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-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.
