What is the primary function of antidiuretic hormone (ADH) or vasopressin in the human body?
A. Stimulates milk production
B. Promotes water reabsorption in renal distal tubules and collecting ducts✓ Correct Answer
C. Increases blood calcium levels
D. Regulates basal metabolic rate
💡 Solution & Explanation
Antidiuretic hormone, also known as vasopressin, is secreted by the posterior pituitary gland and promotes water reabsorption in the distal convoluted tubules and collecting ducts of the nephron, thereby reducing urine output. Other hormones like oxytocin stimulate uterine contractions and milk ejection. Endocrine system functions are important topics in competitive biology.
