Question

A condition known as Pulmonary Hypertension is characterized by high blood pressure in the pulmonary circuit. Which chamber of the heart would this condition most directly affect, and why?

Answer 1

The correct answer will be the right chamber of the heart especially right ventricle.

Step-by-step explanation:

Pulmonary hypertension is the elevated blood pressure in the arteries of the lungs known as pulmonary arterioles. This happens due to the narrowing of the pulmonary arterioles in the lungs and capillaries which could lead to the blockage of arterioles.

This increases pressure in the arterioles and alveolar part of the lungs which is passed down to the right part of the heart especially "right ventricle" which pump deoxygenated blood to the lungs through the pulmonary artery. The right ventricle has to work harder to pump blood to lungs which causes the heart muscle to weaken and fail.

Thus, the right chamber of the heart especially right ventricle is the correct answer.
