Question 1 of 5
Which of the following is not an effect of a hormone secreted by the adrenal gland?
Correct Answer: D

Question 2 of 5
Which of the following can increase blood flow?
Correct Answer: A
Rationale: Larger diameter reduces resistance (F = P/R), increasing flow; others impede it.
Question 3 of 5
Calculate the net filtration pressure (NFP) with a capillary hydrostatic pressure (CHP) of 20 mm Hg and a blood colloid oncotic pressure (BCOP) of 25 mm Hg. Then determine if filtration or reabsorption occurs.
Correct Answer: D
Rationale: NFP = CHP - BCOP = 20 - 25 = -5 mm Hg; negative NFP means reabsorption.
Question 4 of 5
Which of the following structures protects the lower respiratory system from food and fluid bolus during swallowing?
Correct Answer: B
Rationale: Epiglottis closes over glottis during swallowing to prevent aspiration.
Question 5 of 5
Which hormone plays a central role in determining the rate of sodium reabsorption and potassium secretion?
Correct Answer: B
Rationale: Aldosterone increases Na+ reabsorption and K+ secretion in distal nephron.
