Answer 1

$\rm\huge\underline{Answer}$

The heart has four chambers:

The right atrium receives blood from the veins and pumps it to the right ventricle.

The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen.

The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.

The left ventricle (the strongest chamber) pumps oxygen-rich blood to the rest of the body. The left ventricle’s vigorous contractions create our blood pressure
