There is an interesting relationship between plasma and whole blood. Whole blood contains plasma but plasma does not contain whole blood.
When you remove plasma from whole blood, it is just the red blood cells that are left. The plasma will be a sort of yellow liquid taken from the blood.
Hematocrit is the proportion of your total blood volume that is composed of red blood cells. If you add the plasma, what you have is a blood sample called a full blood count.
Plasma is obtained by fractionation of human blood. Plasma contains proteins, clotting factors, and antibodies and is used for various medical purposes, including treating clotting disorders and immune deficiencies.
55% of the whole blood is blood plasma.
This would be whole blood and normal - blood is made of blood cells and plasma (the liquid portion).
By using a centrifuge. I donate platelets, not whole blood and it is done by this method. They spin out what they need. whole blood donations can also be split to help as many as three different patients. You can't derive blood from plasma. You can derive plasma from blood all day long, but you can't derive a whole (blood) from a part (plasma).
It is called whole blood. Whole Blood is Plasma & Formed Elements (RBC's, WBC's, etc) Plasma contributes 46-63% and the Formed Elements contribute 37-54% of whole blood in the body.
The liquid part is plasma and the solid part are the RBCs(red blood corpuscles/cells).
Plasma? Serum?
Plasma is mostly water.
The blood that runs through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55 percent plasma and 45 percent blood cells.
