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

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.

Answer 2

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

Step-by-step 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 * 10^(13)` red blood cells.

1 microliter - x red blod cells.

`4732000x = 2 * 10^(13)`

`x = (2 * 10^(13))/(4732000)`

`x = 4226543`

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