Question

Determine the heart rate, R, of a person whose heart pumps milliliters (ml) of blood per minute and V milliliters of blood per beat.

a) R = V
b) R = 2V
c) R = V/2
d) R = 3V

Answer 1

The heart rate, R, is calculated by dividing the total volume of blood pumped per minute by the volume of blood per beat.

Step-by-step explanation:

To determine the heart rate, R, of a person, we need to understand the relationship between the volume of blood pumped per beat (V) and the total volume of blood pumped per minute. Since the flow rate (Q) is the total volume of blood (V) pumped per unit of time (t), we can express the heart rate (R) as the total volume pumped per minute (in ml/min) divided by the volume of blood per beat (V). Therefore, the correct equation to calculate the heart rate, R, is:
R = Total Volume Pumped per Minute / Volume per Beat.
