Chambers and valves of the heart - Mayo Clinic
3 Oct 2024 at 3:14pm
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 more muscular right and left ventricles, pump blood out of the heart. The heart valves are gates at the chamber openings. They keep blood flowing in the right direction.

Heart rate: What's normal? - Mayo Clinic

A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.

If your heart valve can't be repaired and other treatments aren't an option, the valve might need to be replaced. To replace a heart valve, a surgeon removes the heart valve and replaces it with a mechanical valve or a valve made from cow, pig or human heart tissue. Valves made from living tissue are called biological tissue valves.

The heart squeezes and relaxes. When the heart squeezes, it pumps out ? or ejects ? blood from the two lower heart chambers, called ventricles.
