Question 1 of 5
Which hormone stimulates milk production in the breasts during lactation?
Correct Answer: C
Rationale: Prolactin is the hormone responsible for stimulating milk production in the breasts during lactation. It is produced by the pituitary gland and plays a crucial role in the initiation and maintenance of lactation. While norepinephrine, antidiuretic hormone, and oxytocin have roles in various physiological processes, they do not directly stimulate milk production. Therefore, the correct answer is prolactin.
Question 2 of 5
Which of the following hormones decreases the concentration of blood glucose?
Correct Answer: A
Rationale: Insulin is the hormone responsible for decreasing the concentration of blood glucose levels by promoting the uptake and storage of glucose in cells. When blood glucose levels rise, insulin is released to help cells absorb excess glucose, thereby lowering its concentration in the bloodstream. Glucagon, growth hormone, and glucocorticoids, in contrast, all play roles in increasing blood glucose levels through different mechanisms.
Question 3 of 5
What is the response of cells in the collecting tubules in the nephrons when antidiuretic hormone (ADH) is secreted?
Correct Answer: C
Rationale:
Question 4 of 5
What is the function of aldosterone?
Correct Answer: B
Rationale: Aldosterone is a hormone produced by the adrenal glands that plays a key role in regulating sodium and potassium levels in the body. Its primary function is to conserve sodium by increasing its reabsorption in the kidneys, which helps maintain electrolyte balance and blood pressure. Therefore, the correct answer is B.
