potential and the events described above are repeated in that sequence and the process continues.

Therefore, the cardiac output can be defined as the vole (no. of beats per min.) gives ventricle per minute and averages $5000\mathrm{mL}$ or 5 litres in a healthy individual. the stroke volume as well as the heart rate and thereby the cardiac output. For example, the cability to alter an athlete will be much higher than that of an ordinary man. During outpute of of oxample, the cardiac output of are produced which can be easily heard through a sterdiac cycle two prominent sounds the closure of the tricuspid and bicuspid valthescope.
