Question

In a normal cardiac cycle if stroke volume is 50 ml then what would be the
cardiac output​

Answer 1

Answer:

The cardiac output of a person is calculated by multiplying the stroke volume and the heart rate. Hence, to alter a person’s cardiac output both the stroke volume and the heart rate can be altered. So, the cardiac output of a person having 72 heart beats per minute and a stroke volume of 50 mL would be 72 x 50 = 3600 mL.

Thus, the correct answer is '3600 mL.'

Answer 2

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.

$\boxed {\sf Cardiac \: ou tput \: = Stroke \: volume \: \times Heart \: Rate}$

According to the question the stroke volume is 50ml.

Cardiac output = 50ml × 72 = 3600ml.

thus, the cardiac output is 3600ml.

Note :

$\bigstar$ During cardiac cycle, each ventricle pumps out approximately 70ml of blood which is called the stroke volume.

$\bigstar$ The cardiac output can be defined as the volume of blood pumped out by each ventricle per minute .

$\bigstar$ The body has the ability to alter the stroke volume as well as the heart rate.

$\bigstar$ The cardiac output of an athlete will be much higher than of ordinary man.
