Red blood cells (erythrocytes) travel around the body constantly, they deliver oxygen and remove waste from body tissues, without them the body would not be able to survive.
Red blood cells need to be tiny in size so that they can squeeze through the microscopic capillaries, ensuring that every cell in the body is oxygenated.
There are therefore approximately 5 million red blood cells per cubic millimetre of blood which means that the entire body contains approximately 25 trillion red blood cells!
Well, it depends on your gender. It goes at is:
So it can be anywhere from the minimum to the max or in between. It can also be raised or lowered my certain drugs. It can be raised by:
It can be lowered by:
So there for, it is mostly found between those, but aren't always there. So it's important to keep a healthy, stable red blood cell count.
2.5 x 1013 (give or take a handful!) There are about 5 million red blood cells in every microliter of human blood (on average men have rather more, women slightly fewer). An adult has about 5 liters of blood (= 5 million microliters). So the number of red cells
= 5,000,000 x 5,000,000
= 25 trillion
= 2.5 x 1013
There are about 30 trillion red blood cells in the average human body.
The normal RBC count in Adult
Male : 5-6 million / cu mm
Female : 4.5-5.5 million / cu mm
There are 30 trillion and you probably just gasped :)
The average adult human has about 30-35 trillion red blood cells.
for every 700 red blood cells there is one white blood cell. The 45 percentage of blood is red blood cells.

Red blood cells because that is what carries oxygen throughout the body
If you had insufficient red blood cells, your body would not get the oxygen that it needs. This is because red blood cells are what carries oxygen around the body.
The heart pumps the blood around the body by contracting.
Billions! :)
red blood cells. but there are also many white blood cells. not as many though.
Red Blood Cells
Red blood cells carry oxygen to the cells in your body while the white blood cells fight diseases.
As the name says, red blood cells are found in the blood. If there is blood there, there is red blood cells.
Red blood cells carry oxygen to the body cells.
