fsh
tsh
gh
prolactin
question 6 (2.5 points)
a hormone that regulates the sodium ion concentration of the blood is
cortisol
aldosterone
thyroxine
thymosin

Explanation:

First Question (Pituitary Hormone for Milk Production)

• FSH (Follicle - Stimulating Hormone) is involved in reproductive processes like follicle development in ovaries and sperm production in testes, not milk production.
• TSH (Thyroid - Stimulating Hormone) stimulates the thyroid gland to produce thyroid hormones, not related to milk production.
• GH (Growth Hormone) is mainly for growth and metabolism regulation, not milk production.
• Prolactin is the pituitary hormone that specifically stimulates milk production by mammary glands.

• Cortisol is involved in stress response, metabolism regulation, etc., not sodium ion concentration regulation.
• Aldosterone, a hormone from the adrenal cortex, acts on the kidneys to increase sodium reabsorption, thus regulating blood sodium ion concentration.
• Thyroxine is from the thyroid gland and regulates metabolism, not sodium levels.
• Thymosin is involved in T - cell development in the thymus, not sodium regulation.

Answer:

D. prolactin
