Q

Pancreas

A

Exocrine: digestive enzymes (amylase, lipase, trypsin, chymotripsin) and bicarbonate

Endocrine: Insulin (remove glucose from blood & convert glucose to glycogen) and glucagon (breakdown of glycogen to glucose)

(Occurs in islets of Langerhans)

Q

FSH

A

Spurs maturation of seminiferous tubules

Stimulates follicle growth. Mature follicle produces estrogen.

First stage of menstrual cycle

Surge in LH secretion from pituitary causes ovulation

Q

Progesterone

A

Readies the uterus for implantation

Production stops if LH stops and corpus luteum atrophies (no fertilization/implantation)

If implantation occurs hCG (human chorionic gonadotrophic hormone) maintains corpus luteum (maintains progesterone and estrogen)

Q

LH

A

Luteinizing hormone

From pituitary

Surge causes ovulation

After ovulation remains of follicle in ovary create corpus luteum

LH stimulates corpus luteum to produce progesterone and estrogen

If no implantation occurs, estrogen and progesterone block LH and corpus luteum atrophies

Progesterone falls when luteum atrophies and uterine wall breaks down

Male- maturation of testes

Q

ADH

A

Antidiuretic hormone- released in dehydration to make urine more concentrated (makes collecting duct more permeable)

Q

Aldosterone

A

Produced in adrenal cortex, steroid

Conserves water and sodium (secretion of potassium)

Leads to rise in blood volume and pressure

Acts by increasing reabsorption of sodium in distal tubule

Q

Adrenal glands

A

ADRENAL CORTEX: corticosteroids secreted in response to ACTH (stress)

Glucocorticoids-
Cortisol and cortisone
raise blood glucose, decrease protein synthesis, repress immune system

Mineralocorticoids-
Aldosterone
regulate plasma levels of sodium and potassium

Androgens

ADRENAL MEDULLA: specializes sympathetic nerve cells

Epinephrine (adrenaline) and Norepinephrine (noradrenaline)- conversion of glycogen to glucose, increase nasal metabolic rate, increase blood to skeletal muscles, heart, and brain
