Study Notes
Blood Composition and Properties
- The average adult has a total blood volume of approximately 5 liters.
- The yellow liquid portion of clotted blood is called serum.
- When blood is artificially removed from the body for testing, it is called phlebotomy.
- Erythrocytes or red blood cells (RBCs) make up approximately 45% of the whole blood volume.
- Anticoagulant is added to blood removed from the circulation via phlebotomy to create a whole blood specimen.
- The plasma layer, comprising approximately 55% of the total volume, forms on top of the cells.
- The major difference between plasma and serum is the presence of clotting factors, which are absent in serum.
- Plasma is composed of approximately 92% water, 7% protein, and 1% other substances by weight.
- All blood cells, including leukocytes (white blood cells) and platelets, originate in the bone marrow.
- The three major maturational stages of blood cells are: myeloid stem cell, precursor cell, and mature blood cell.
