in any given mm3 of blood, what is the approximate ratio of the number of red blood cells (erythrocytes) to white blood cells (leukocytes)
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.
Macrocytosis is the term given for the condition of having larger blood cells than normal. It is not a disease but can be the symptom of a number of underlying medical conditions.
White blood cells (WBCs) are another infection-fighting component of the blood. White blood cells are given by transfusion only rarely.
Red cells = erythrocytes White cells = leukocytes
They are given to people who have anemia (including thalassemia ), whose bone marrow does not make enough RBCs, or who have other conditions that decrease the number of RBCs in the blood.
Blood is approximately 55% plasma45% RBC's1% WBC's
Ther are equal numbers of red and white
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.
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%.

Blood Cells?
White blood cells (WBCs) are another infection-fighting component of the blood. White blood cells are given by transfusion only rarely.
CBC on lab tests refers to "complete blood count" and will measure the number of red and white blood cells, as well as platelets, per given amount of blood.
Red cells = erythrocytes White cells = leukocytes
They are given to people who have anemia (including thalassemia ), whose bone marrow does not make enough RBCs, or who have other conditions that decrease the number of RBCs in the blood.
Yes. O negative red cells can be given to any other blood type.
