Question

Normal levels of oxytocin are around ______ pg/mL, while normal levels of ADH are around _______ pg/mL.

A) 10; 50
B) 100; 500
C) 1,000; 10,000
D) 5; 20

Answer 1

Normal oxytocin levels are approximately 5 pg/mL, and ADH levels are around 20 pg/mL. The hormones, produced by the pituitary gland, have distinct functions such as water retention for ADH and induction of labor for oxytocin.

Step-by-step explanation:

Normal levels of oxytocin are around 5 pg/mL, while normal levels of ADH (antidiuretic hormone) are around 20 pg/mL. Therefore, the correct answer is D) 5; 20.

Vasopressin, also known as ADH, is crucial for water homeostasis in the body. It acts on the kidneys to conserve water by making the ducts more permeable, resulting in more concentrated urine. On the other hand, oxytocin plays a critical role during childbirth by inducing uterine contractions and also stimulates the letdown of milk in breastfeeding mothers. Both hormones are produced by the pituitary gland and are essential for the maintenance of different physiological processes.
