Question

If the human body has 5.0 qt of blood that contains 2 x 10 13 red blood cells, how many red blood cells are present in each microliter of blood?

Answer 1

Answer:

In each microliter of blood, there are 4,226,543 red blood cells

Explanation:

This question can be solved by a rule of three.

Each quart has 946353 microliters

The human body has 5 qt of blood. Since each quart is worth 946353 microliters

5*946353 = 4732000 microliters.

4732000 microliters - $2 \times 10^{13}$ red blood cells.

1 microliter - x red blod cells.

$4732000x = 2 \times 10^{13}$

$x = \frac{2 \times 10^{13}}{4732000}$

$x = 4226543$

In each microliter of blood, there are 4,226,543 red blood cells

Answer 2

Adult humans have roughly 20–30 trillion red blood cells at any given time. Women have about 4–5 million red blood cells per microliter. en about 5–6 million; people living at high altitudes with low oxygen tension will have more.
