Question

At the time of interview, heart beat increases due to:
A. ADH secretion
B. secretion of renin
C. secretion of adrenaline
D. Adrenocorticotropic hormone

Answer 1

Stress is a situation which tries to disturb the equilibrium or balance between a living organism and its environment. In stressful situations, like work pressure, examination, interviews or any medical disorders, hormone level in the body is enhanced, which leads to secretion of various hormones.

Complete step by step answer:
-ADH secretion – ADH secretion is a short form of Antidiuretic Hormone, also known as arginine vasopressin. It is made by special nerve cells of the brain known as hypothalamus. It is transferred to the pituitary gland which releases it into the bloodstream. When a decrease in blood volume is observed, ADH is released, the kidney responds to it, and conserves water in the body by releasing concentrated urine. So, it has no role in the interview situation. Hence, option (a0 is incorrect.
- Secretion of renin – Renin is an enzyme secreted by the kidney. It is released when there is a fall in the arterial blood pressure or when a decrease in the Sodium Chloride level is detected. It releases a hormone renin which regulates the blood pressure. So, it has no role in the interview situation. Hence, option (b) is incorrect.
-Secretion of adrenaline – Adrenaline hormone is released by the adrenal gland when the nerve connected to it gets activated due to some stressful situations. When it is released, the body shows some symptoms to respond to the stressful situation. These symptoms include rapid heartbeat, anxiety, high blood pressure, excessive sweating, etc. So, secretion of adrenaline is responsible for increased heartbeats during an interview. Hence, option (c) is correct.
- Adrenocorticotropic hormone – It is commonly called ACTH. It is made in the pituitary gland. For proper functioning of the adrenal gland which helps the body to react stress, ACTH is needed. A deficiency of ACTH in the blood leads to less secretion of adrenal hormones. Thus, it is not directly related to increased heartbeat during interviews. So, option (d) is incorrect.
Hence, option (c) is the correct answer for increasing heartbeat during an interview.

Note: Stressful situations also stimulate the release of a steroid hormone called cortisol from the cortex of the adrenal gland. This steroid plays a key role in altering the metabolism of the human body.
