Solution
The correct option is D Angiotensin II
When the blood volume and blood pressure decrease, juxtaglomerular cells in the kidneys secrete the enzyme renin. Renin catalyzes the conversion of angiotensinogen to angiotensin II. Angiotensin II stimulates the adrenal cortex to release aldosterone.
Aldosterone promotes the absorption of NaCl and water from distal convoluted tubule (DCT). This reabsorption of water leads to an increase in blood volume inturn blood pressure.
Antidiuretic hormone, ADH (vasopressin) is released by the posterior pituitary lobe when the blood has high osmolarity.
So, the correct answer is -angiotensin II.
