Match the source gland with its respective hormone as well as the function.
A
Thyroid – Thyroxine – Regulates blood calcium level
B
Anterior pituitary – Oxytocin – Contraction of uterus muscles during child birth
C
Posterior pituitary – Vasopressin – Stimulates resorption of water in the distal tubules in the nephron
D
Corpus luteum – Estrogen – Supports pregnancy
Detailed Solution
Vasopressin (ADH) is synthesised in the hypothalamus but is stored in and released from the posterior pituitary; it stimulates reabsorption of water in the distal tubules of the nephron and so reduces loss of water in urine. This row is fully correct.
Thyroxine from the thyroid regulates the basal metabolic rate; blood calcium is regulated by thyrocalcitonin (and parathyroid hormone).
Oxytocin does cause contraction of the uterus during child birth, but it is released from the posterior pituitary, not the anterior pituitary.
The corpus luteum secretes mainly progesterone, which supports pregnancy.
Hence the correct match is posterior pituitary – vasopressin – stimulates resorption of water in the distal tubules.
