Question

Blood pressure is controlled by

• A. Thyroid gland
• B. Adrenal gland
• C. Thymus gland
• D. Parathyroid gland

Answer 1

The correct option is B

Adrenal gland

The correct option is B

Explanation of the correct option:

1. Aldosterone is a steroid hormone (mineralocorticoid) produced by the outer section (zona glomerulosa) of the adrenal cortex in the adrenal gland.
2. 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, causing the conservation of sodium, secretion of potassium, increasing in water retention, and increase in blood pressure and blood volume.

Explanation of the incorrect option:

Option A:

The thyroid gland is a vital hormone gland: It plays a major role in the metabolism, growth, and development of the human body.

Option C:

The thymus produces progenitor cells that develop into T-cells. These T-cells help the body fight against infections. They also aid in the growth of other organs in the immune system.

Option D:

Parathyroid glands produce parathyroid hormone, which plays a key role in the regulation of calcium levels in the blood.

Final answer: Blood pressure is controlled by the adrenal gland
