Atypical human contains 5.00 l of blood, and it takes 1.00 min for all of it to pass through the heart when the person is resting with a pulse rate of 74.0 heartbeats/ minute. on the average, what volume of blood, in (a) liters and (b) cubic centimeters, does the heart pump during each beat?

Volume of blood, in (a) liters = 0.0675 liters and (b) cubic centimeters = 67.5 cm³

7 main quantities have been determined based on international standards, namely:

1. Length, meters (m)

2. Time, second (s)

3. Mass, kilograms (kg)

4. Temperature, kelvin (K)

5. Light intensity, candela (cd)

6. Electric current, ampere (A)

7. Amount of substance, mol (m)

The length of the principal is to indicate the distance between two points in a place

The symbol is usually expressed in l, length

Volume is a derivative quantity derived from the length of the principal

The unit of volume can be expressed in liters or milliliters or cubic meters

The conversion is

1 cc = 1 cm³

1 dm = 1 Liter

1 mL = 1 cm³

1 L = 1 dm³

From the question, 5 liters of blood passes through the heart in 1 minute

The heart beats 74 times/minute

So that the equation is easy as follows:

5 liters = 1 minute

74 beats = 1 minute

So that in 1 heartbeat there is as much blood volume as:

= 5 liters / 74 beats

= 0.0675 liters

When we convert to cm³ it becomes:

1 L = 1 dm³ = 10³ cm³

0.0675 liters = 0.0675.10³ cm³

= 67.5 cm³
