Question

If the heartbeat of a person is about 75 beats per minute, and stroke volume is 70 mL per minute, then the cardiac output will be (A) 5000 mL (B) 5250 mL (C) 5500 mL (D) 5150 mL

Tardigrade Admin · Accepted Answer

The stroke volume multiplied by the heart rate (no. of beats per min.) gives the cardiac output.
In the given question:
The stroke volume is 70 mL, while the heart rate is 75 beats per minute.
Cardiac output = Stroke volume x Heart rate
= 70 x 75 = 5250 mL

Q. If the heartbeat of a person is about 75 beats per minute, and stroke volume is 70 mL per minute, then the cardiac output will be

5000 mL

5250 mL

5500 mL

5150 mL

The stroke volume multiplied by the heart rate (no. of beats per min.) gives the cardiac output. In the given question: The stroke volume is 70 mL, while the heart rate is 75 beats per minute. Cardiac output = Stroke volume x Heart rate = 70 x 75 = 5250 mL

The stroke volume multiplied by the heart rate (no. of beats per min.) gives the cardiac output.
In the given question:
The stroke volume is 70 mL, while the heart rate is 75 beats per minute.
Cardiac output = Stroke volume x Heart rate
= 70 x 75 = 5250 mL
