The chambers that receive blood are the right and left atria.
Heart Chambers and Blood Flow
The heart has four chambers crucial for circulating blood throughout the body. These chambers work in a coordinated manner to ensure efficient blood flow. According to the provided reference:
- The upper chambers, the right and left atria, receive incoming blood.
- The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.
- Heart valves, positioned at the chamber openings, act as gates to maintain unidirectional blood flow.
In summary, the atria are responsible for receiving blood, while the ventricles pump it out.
