Question 26

adrenal cortex secretes

Answer 26

steroid hormones like aldosterone and cortisone ***AC -> AC

Question 27

adrenal medulla secretes

Answer 27

epinephrine (adrenalin) and norepinephrine ***AMEN

Question 28

Glomerular filtration rate (GFR)

Answer 28

filtrate produced per minute by both kidneys; the work rate of the kidney

Question 29

Antidiuretic hormone (ADH)

Answer 29

Excreted by the posterior pituitary in the brain and increases H2O resorption by the kidney

Question 30

Aldosterone
