Match the following blood analysis terms with their definitions:
Hematocrit (PCV) = An estimate of the volume of packed erythrocytes per unit volume of blood. Clot = What occurs if blood is removed from the circulatory system. Serum = Clear yellow liquid that separates from the clot. Anticoagulant = Material that prevents blood from clotting when collected.

Match the following blood analysis processes with their outcomes:
Blood removal = It will clot. Blood with anticoagulant = It will not clot. Centrifugation of anticoagulated blood = It will separate into about 3 layers. Separation of clot = Results in formed elements and serum.

Study Notes
Hematocrit (PCV)
- An estimate of the volume of packed red blood cells per unit volume of blood.
Blood Clotting
- Blood removed from the circulatory system will clot.
Clot Composition
- Clots contain formed elements and clear yellow liquid called serum, that separates from the clot.
Anticoagulants
- Blood collected in a tube containing an anticoagulant will not clot.
Blood Centrifugation
- Blood with an anticoagulant, when centrifuged, will separate into about 3 layers.
Lowest Red Layer Composition
- The lowest red layer is composed of erythrocytes and makes up about 40-45% of the blood.
Second Layer Description
- The second layer is translucent, yellowish and is the supernatant plasma.
Buffy Coat
- The thin layer between the two layers is known as the buffy coat.
