in 1cm3 of blood, there are 5 000 000 000 red blood cells and 8 000 000 white blood cells. so- 5000:8.
in any given mm3 of blood, what is the approximate ratio of the number of red blood cells (erythrocytes) to white blood cells (leukocytes)
In 1cm3 of blood, there are 5,000,000,000 red blood cells and 8,000,000 white blood cells. Meaning a ratio of 5000 to 8.
Ther are equal numbers of red and white
Blood is approximately 55% plasma45% RBC's1% WBC's

There are about a thousand times as many red blood cells as white cells. Consider that the red blood cells (or erythrocytes) in a mm3 (or microliter) of blood number about five million in an average man (a few less in a woman). The white blood cells (or leukocytes) number only 5-6 thousand per mm3 so the ratio is about a thousand fold.
The normal ratio of red blood cells (RBCs) to white blood cells (WBCs) in the human body is approximately 700:1. However, this ratio can change based on various factors such as dehydration, medical conditions, or medication use. If the ratio deviates significantly from this range, it may indicate an underlying health issue that requires further investigation.
Blood cells are predominantly red cells. They outnumber the white cells by a factor of 1000:1 to 2000:1 in normal humans. The composition of blood is 55% plasma and 45% formed elements. The formed elements are mostly red blood cells, which make up 44% of total blood volume. The remaining 1% consists of white blood cells and platelets. Appx. 700:1 Blood consists of formed elements (red blood cells, white blood cells and platelets) and plasma. Red blood cells (erythrocytes) account for 99.9% of cells. Plasma 55%, and Cells 45%.
That is what I am wondering!
there is about a 1000 to 1 to 2000 to 1 ratio of RBCs to WBCs
I n any givien mm3 of blood, what is the approximate ratio of the number of red blood cell to white blood cells?
1,000,000,000,000,000,000:1
