Figure shows human urinary systemwith structures labelled A to D. Select option, which correctly identifies them and gives their characteristics and/of functions

  • A - adrenal gland - located at the anterior part of kidney. Secrete catecholamines, which stimulate glycogen breakdown

  • B - pelvis - broad funnel shaped space inner to hilum, directly connected to loops of Henle

  • C - mediulla - inner zone of kidney and contains complete nephrons

  • D - cortex - outer part of kidney and do not contain any part of nephrons

Solution

A.

A - adrenal gland - located at the anterior part of kidney. Secrete catecholamines, which stimulate glycogen breakdown

A - adrenal gland- 

B - Renal pelvis - The renal pelvis or pelvis of the kidney is the funnel-like dilated part of the ureter in the kidney. In humans, the renal pelvis is the point where the two or three major calyces join together.

C - Medulla - The renal medulla is the innermost part of the kidney. The renal medulla is split up into a number of sections, known as the renal pyramids. Blood enters into the kidney via the renal artery, which then splits up to form the interlobar arteries.

D - Cortex - 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. The renal cortex is the part of the kidney where ultrafiltration occurs. Erythropoietin is produced in the renal cortex.
