Which hormone is released by the kidney and stimulates the production of red blood cells?

ANF
Erythropoietin
Vasopressin
Melatonin
2

Erythropoietin, secreted by the kidney, stimulates bone marrow to produce red blood cells.

Which hormone is secreted by the corpus luteum and helps in the maintenance of pregnancy?

Estrogen
Progesterone
FSH
Oxytocin
2

Progesterone, secreted by the corpus luteum, helps maintain pregnancy by supporting the uterine lining.

Which hormone is secreted by the parathyroid gland and increases blood calcium levels?

Calcitonin
Parathyroid Hormone (PTH)
Thyroxine
Insulin
2

PTH increases blood calcium levels by stimulating calcium release from bones and increasing absorption in the intestines.

What is the function of melanocyte-stimulating hormone (MSH)?

Regulation of blood calcium levels
Regulation of metabolic rate
Control of pigmentation in the skin
Regulation of heart rate
3

Melanocyte-stimulating hormone (MSH) regulates pigmentation of the skin by acting on melanocytes.

Which hormone is responsible for stimulating the production of red blood cells?

Cortisol
Erythropoietin
Glucagon
Testosterone
2

Erythropoietin, secreted by the kidneys, stimulates the bone marrow to produce red blood cells.

Which hormone is responsible for stimulating the secretion of glucocorticoids from the adrenal cortex?

FSH
LH
ACTH
TSH
3

Adrenocorticotropic hormone (ACTH) stimulates the adrenal cortex to release glucocorticoids like cortisol.

Which hormone is secreted by the adrenal cortex and regulates electrolyte balance?

Glucagon
Aldosterone
Insulin
Oxytocin
2

Aldosterone, secreted by the adrenal cortex, regulates sodium and potassium balance in the body.

Which hormone is responsible for stimulating the adrenal cortex to produce cortisol?

Thyroid-stimulating hormone (TSH)
Luteinizing hormone (LH)
Adrenocorticotropic hormone (ACTH)
Follicle-stimulating hormone (FSH)
3

ACTH stimulates the adrenal cortex to secrete cortisol, which helps in metabolism and stress response.

Which hormone is responsible for uterine contractions during childbirth?

Oxytocin
Progesterone
LH
TSH
1

Oxytocin, released by the posterior pituitary, stimulates powerful contractions of the uterus during childbirth.

Which of the following statements about glucagon is correct?

Glucagon promotes glycogen breakdown in the liver.
Glucagon lowers blood glucose levels.
Glucagon is secreted by beta cells of the pancreas.
Glucagon and insulin have the same function.
1

Glucagon, secreted by alpha cells of the pancreas, promotes glycogen breakdown to increase blood glucose levels.
