Define a cardiac cycle and the cardiac output. |
|
Answer» Cardiac cycle. A regular sequence of three events : (i) auricular systole, (ii) ventricular systole, and (iii) joint diastole or complete cardiac diastole (relaxation of both auricles and ventricles) during the completion of one heart beat is known as heart cycle or Cardiac cycle. Cardiac output. The volume of blood pumped by the left ventricle into the systemic circuit per minute is called cardiac output or heart output. Heart beats 72 times per minute and pumps out about 70 ml of blood during each beat. Therefore, `72xx70` or 8040 ml (roughly 5 litres) is the Cardiac output. |
