Question

(b) Explain how the difference in the pressure of the blood in the pulmonary artery and in the
Aorta is related to
(i) the structure of the ventricles​

Answer 1

Answer:

Did you mean: Explain how the difference in the pressure of the blood in the pulmonary artery and in the Aorta is related to (in) the structure of the ventricles

Normally the pressure on the right side of the heart and in the pulmonary arteries is lower than the pressure on the left side of the heart and in the aorta. This is because: the right side of the heart pumps blue (deoxygenated – little or no oxygen) blood returning from the body back to the lungs.

Answer 2

A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli.
