8. The Components of Blood and Their Importance (52s)

9. Blood Volume Blood volume varies with: Body size
Changes in fluid and electrolyte concentration
Amount of adipose (Fat) tissue
Makes up about 8% of body weight
Average size adult has about 5 liters

10. Blood Composition
If a blood is prevented from clotting, the cells separate from the liquid portion of the blood and settle at the bottom
A Centrifuge quickly packs the cells into the lower part of the centrifuge tube
The percentage of cells and liquid in the blood sample can then be calculated and used for diagnostic purposes.

11. Blood Composition A blood sample is usually about:
45% RBC --This % is called the hematocrit or HCT
> 1% WBCs/ platelets
55% Plasma
