Vedclass · Answer

(C) : In the given figure, $A$ is the adrenal gland which secretes two catecholamines; adrenaline (epinephrine) and noradrenaline (norepinephrine). Adrenaline increases the conversion of glycogen to glucose, providing quick energy for the "fight or flight" response. $B$ is the renal pelvis, which is a sac-like cavity of the kidney leading to the ureters; it is not directly connected to the loop of Henle. $C$ is the medulla, the inner region of the kidney containing the loop of Henle, collecting ducts, and ducts of Bellini. $D$ is the cortex, which has proximal and distal convoluted tubules and contains Malpighian corpuscles.

The figure shows the human urinary system with structures labelled $A$ to $D$. Select the option which correctly identifies them and gives their characteristics and/or functions.
