Question

# Which of the following blood vessels carries blood with the highest pressure?

A

Pulmonary veins

B

Superior vena cava

C

Pulmonary artery

D

Inferior vena cava

Solution

## The correct option is B Pulmonary arteryThe rest of the blood vessels mentioned carry blood back to the heart, and therefore carry blood at much lower pressure. The pulmonary artery and the aorta, on the other hand, carry blood out of the heart, and therefore carry blood at tremendous pressure owing to the systolic pressure of the ventricles.Biology
