Study Notes

The heart has four chambers: two atria and two ventricles.
Blood enters the heart through the atria, which then contract and pump blood to the ventricles.
The right side of the heart pumps deoxygenated blood to the lungs via the pulmonary circulation.
The left side of the heart receives oxygenated blood from the lungs and pumps it to the rest of the body.
The heart acts as a dual pump, one side sending blood to the lungs for oxygen and the other side sending blood to the body.
Oxygen is transferred to the blood in the lungs through diffusion across the alveoli.
Blood is circulated through the body, used up for oxygen, returns to the heart, and the process repeats simultaneously.

Description

Learn about the anatomy of the heart which consists of two atria and two ventricles. Explore how blood circulates through the heart, lungs, and the rest of the body, picking up oxygen and delivering it to cells. Understand the role of the heart as a dual pump for systemic and pulmonary circulation.
