Question

Blood pressure is controlled by

• A. Adrenal gland
• B. Thyroid gland
• C. Pituitary gland
• D. None of the above

Answer 1

The correct option is A Adrenal gland

Aldosterone is a steroid hormone (mineralocorticoid) produced by the outer section (zona glomerulosa) of the adrenal cortex in the adrenal gland. It plays a central role in the regulation of blood pressure mainly by acting on the distal tubules and collecting ducts of the nephron, increasing reabsorption of ions and water in the kidney, to cause the conservation of sodium, secretion of potassium, increase in water retention, and increase in blood pressure and blood volume.
