How many times does a heartbeat in a minute?
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.
How many times does the heart pump blood in one minute?

Where does deoxygenated blood come from?
The ventricles are the two lower chambers of the heart. Blood empties into each ventricle from the atrium above, and then shoots out to where it needs to go. The right ventricle receives deoxygenated blood from the right atrium, then pumps the blood along to the lungs to get oxygen.
Is 4 units of blood a lot?
