Question

Given below is the figure showing the human urinary system with structures labelled A to D. Select the option which correctly identifies them and gives their function.

 

Options

• C - Medulla - contains complete nephrons.

• D - Cortex - does not contain any part of nephrons.

• A - Adrenal gland - secretes catecholamines which stimulate glycogen breakdown.

• B - Pelvis - directly connected to the loop of Henle.

Answer 1

A - Adrenal gland - secretes catecholamines which stimulate glycogen breakdown.

Explanation:

The correct labelling of A - Adrenal gland. B and C - Medullary pyramids/medulla. D-Cortex.

• False, because the medulla contains a Henle loop, PCT, and DCT of the nephron.
• False, because the cortex contains the malpighian corpuscle, the PCT, and the DCT.
• True
• False, because (B) is the medullary pyramid.
