11 cze 2024 · Summary. The heart is the pump that moves blood around your body. It has four main parts: two upper chambers called atria and two lower chambers called ventricles. These parts work together to get oxygen-rich blood to your body and oxygen-poor blood back to your heart.
The diagram illustrating the blood flow through the heart shows the various chambers and valves that ensure efficient circulation. The heart consists of four chambers: two atria (left and right) and two ventricles (left and right). The atria receive deoxygenated blood, while the ventricles pump oxygenated blood out to the body.
