  1. A.Same as that in the aorta
  2. B.More than that in the carotid
  3. C.More than that in the pulmonary vein✓
  4. D.Less than that in the venae cavae

Correct Answer

(C) More than that in the pulmonary vein

Solution & Explanation

Answer: (c) More than that in the pulmonary vein Solution: Blood pressure always falls along the vascular route from artery to vein. The deoxygenated blood pumped by the right ventricle enters the pulmonary artery at higher pressure, passes to the lungs, and is then carried at lower pressure by the pulmonary veins to the left atrium. So pressure in the pulmonary artery is greater than in the pulmonary vein. NCERT: Ch 15, p.201, line 37 — "The deoxygenated blood pumped into the pulmonary artery is passed on to the lungs"
