what is a cardiac cycle? how much blood is pumped in each cardiac cycle ?​

Answer 1

Answer:

Ok sure mate

Explanation:

Cardiac output is the volume of blood being pumped by the heart in a minute. It is equal to the heart rate multiplied by the stroke volume. So if there are 70 beats per minute, and 70 ml blood is ejected with each beat of the heart, the cardiac output is 4900 ml/ minute.

The periodic relaxation (diastole) and contraction (systole) of the heart muscles comprises the cardiac cycle. Each cardiac cycle pumps around 70 ml of blood.
