Answer 2

Explanation:

A muscular organ the size of a fist, the heart is situated directly below and to the left of the breastbone. The cardiovascular system is the web of arteries and veins through which the heart pumps blood.

Four chambers make up the heart:

• Blood is drawn from the veins and pumped to the right ventricle via the right atrium.
• Blood from the right atrium is taken up by the right ventricle, which then pumps it to the lungs where oxygen is added.
• Blood that has been oxygenated by the lungs enters the left atrium and is pumped to the left ventricle.
• Blood enriched in oxygen is pumped to the rest of the body by the left ventricle, which is the strongest chamber. Our blood pressure is produced by the forceful contractions of the left ventricle.
