Question

Match the source gland with its respective hormone and function and select the correct option.

• A. Posterior pituitary – Vasopressin – Stimulates the reabsorption of water in the distal tubules in the nephron.
• B. Anterior pituitary – Oxytocin – Contraction of uterus muscles during childbirth.
• C. Thyroid – Thyroxine – Regulates blood calcium level.
• D. Corpus luteum – Estrogen – Supports pregnancy

Answer 1

The correct option is A

Posterior pituitary – Vasopressin – Stimulates the reabsorption of water in the distal tubules in the nephron.

The correct option is A.

Explanation for the correct option:

Option A:

1. The posterior pituitary contains two hormones, oxytocin and vasopressin, which are produced by the hypothalamus.
2. Vasopressin is known as an antidiuretic hormone, which induces water reabsorption from the distal convoluted tubule and prevents water loss.

Explanation for the incorrect options:

Option B:

The posterior pituitary stores and releases oxytocin, and it leads to the contraction of uterus muscles during childbirth.

Option C:

1. The thyroid gland releases the hormone thyroxine, which helps in the proper functioning of the heart and digestive system, metabolism, brain development, bone health, and muscle control.
2. Thyrocalcitonin regulated blood calcium levels.

Option D:

The Corpus luteum releases the progesterone, which prepares the uterus for pregnancy.

Final answer: The correct option for the source gland with its respective hormone and function is Posterior pituitary – Vasopressin – Which stimulates the reabsorption of water in the distal tubules in the nephron.
