Luteinizing hormone (LH) is secreted by which gland and what is its function?

pituitary gland (anterior); in females, stimulates ovulation and controls menstruation; in males, stimulates the production of testosterone.

pituitary gland (anterior); stimulates the thyroid gland and helps regulate thyroid function

pituitary gland (posterior); stimulates the kidneys to retain water and constricts blood vessels

pituitary gland (anterior); helps regulate reproductive processes including puberty

Parathyroid hormone (PTH) is secreted by which gland and what is its function?

parathyroid glands; increases blood calcium levels and stimulates the breakdown of bone

pituitary gland (anterior); helps regulate reproductive processes including puberty

pituitary gland (posterior); stimulates the kidneys to retain water and constricts blood vessels

pituitary gland (anterior); stimulates the thyroid gland and helps regulate thyroid function

Follicle-stimulating hormone (FSH) is secreted by which gland and what is its function?

pituitary gland (anterior); helps regulate reproductive processes including puberty

pituitary gland (posterior); stimulates the kidneys to retain water and constricts blood vessels

pituitary gland (anterior); stimulates milk production and breast development in females

pituitary gland (anterior); stimulates the thyroid gland and helps regulate thyroid function

Cortisol is secreted by which gland and what is its function?

adrenal glands (adrenal cortex); regulates blood glucose levels and helps metabolize carbohydrates, proteins, and fats

adrenal glands (adrenal cortex); regulates blood pressure, electrolyte concentrations, and fluid volume in the body

pituitary gland (anterior); stimulates milk production and breast development in females

adrenal glands (adrenal medulla); intensifies stress and triggers the body's "fight-or-flight" response, causing increased heart rate, blood pressure, and respiration

Insulin is secreted by which gland and what is its function?

pancreas; regulates the absorption of glucose into blood cells, decreasing blood glucose levels

ovaries; stimulates the development of female secondary sex characteristics and regulates the female reproductive system
