the oxygen and carbon dioxide
FUNCTIONS OF BLOOD
- Delivers important nutrition needed
- Carries waste products to be excreted ○
Particularly urine
Functions of Blood
- Has a buffering action in maintaining the overall
blood pH - Transports hormones and acts in defense
mechanism - Participate in the coagulation assays especially
of platelets and clotting factors
FUNCTIONS OF BLOOD
form of tissue since it is composed of different type of cells plus some solutes that helps in performing its functions.
Blood
one of the procedures being performed to separate the blood cells based on their Specific Gravity.

Plasma/Serum
Made up of 90% water and 10% solutes that
carries and transports coagulation enzymes, proteins, lipids,hormones and responsible for nourishing blood cells
Plasma/Serum
From unclotted blood
- Contains fibrinogen because there is no
consumption of fibrinogen
- EDTA - Anticoagulated Tube
- Comes from anticoagulated sample
Plasma
From a clotted blood
No presence of fibrinogen because it is consumed for the clotting
SST (Serum Separator Tube) - thixotropic gel helps in clotting
Comes from non-anticoagulated sample
Serum
Pale yellow
Normal
slight hemolysis due to release of
hemoglobin
