ANATOMY

Detailed explanation-1: -The lower chambers-the right and left ventricles-pump blood out of your heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings (for the tricuspid and mitral valves) and exits (for the pulmonary and aortic valves).

Detailed explanation-2: -There are two atria (upper chambers) called your right atrium and left atrium. In addition, there are two ventricles (lower chambers) called your right ventricle and left ventricle. Each chamber plays an important role in your heart’s functioning.

Detailed explanation-3: -The heart has four chambers. The upper two chambers are the atria, and the lower two are the ventricles (Figure A).

Detailed explanation-4: -The left ventricle is the largest and strongest chamber in your heart. The left ventricle’s chamber walls are only about 1.0 to 1.3cm, but they have enough force to push blood through the aortic valve and into your body.

Detailed explanation-5: -The two lower chambers are called the ventricles, and are separated into the right and left ventricle by the ventricular septum. The ventricles have thicker walls and pump blood to the lungs and body.
