The total blood volume of a human is 75 ml/kg. If the volumetric flow rate is the same in adults and children, how much more blo
Tema [17]

The amount of blood that flows through the venae cavea of the adult is 3750 ml more than that of the child.

<h3>What is flow rate?:</h3>

This is the volume of fluid flowing in a vessel per unit time.

First, we need to get the volume of blood flowing through the venae cavae of the adult and the child in 1 hour, then subtract the volume of blood for the child from that of the adult.

Using,

  • V = F'm................ Equation 1

Where:

  • V = Volume of the blood
  • F' = Flow rate
  • m = mass of blood.

For the Adult,

Given:

  • m = 70 kg
  • F = 75 ml/kg

Substitute these values into equation 1

  • V = 70(75)
  • V = 5250 ml.

For the child,

Given:

  • m = 20 kg
  • F = 75 ml/kg

Substitute these values into equation 1 also

  • V = 75(20)
  • V = 1500 ml.

The amount of blood that flows more through the adult than the child is

  • A = 5250-1500
  • A = 3750 ml.

Hence, the amount of blood that flows through the venae cavea of the adult is 3750 ml more than that of the child.
