In a normal cardiac cycle if stroke volume is 50 ml then what would be thecardiac output |
|
Answer» The CARDIAC output of an individual can by calculated by the product of stroke VOLUME and HEART beat. Normally, the heart beats 72 times per minute.According to the question the stroke volume is 50ml.Cardiac output = 50ml × 72 = 3600ml.thus, the cardiac output is 3600ml.Note : During cardiac cycle, each ventricle pumps out approximately 70ml of BLOOD which is called the stroke volume. The cardiac output can be defined as the volume of blood pumped out by each ventricle per minute . The body has the ability to alter the stroke volume as well as the heart RATE. The cardiac output of an athlete will be much higher than of ordinary man. |
