ANATOMY

Detailed explanation-1: -A typical heart has two upper and two lower chambers. The upper chambers-the right and left atria-receive incoming blood. The lower chambers-the right and left ventricles-pump blood out of your heart.

Detailed explanation-2: -The left ventricle pumps the oxygen-rich blood to the body.

Detailed explanation-3: -aortic valve-on the left side. mitral valve-on the left side. pulmonary valve-on the right side. tricuspid valve-on the right side.

Detailed explanation-4: -The normal heart is a strong, hard-working pump made of muscle tissue. It’s about the size of a person’s fist. The heart has four chambers. The upper two chambers are the atria, and the lower two are the ventricles (Figure A).

Detailed explanation-5: -The right ventricle pumps the oxygen-poor blood through the pulmonary valve to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it through the mitral valve to the left ventricle. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
