Answer
Whole blood consists of plasma and cellular components, blood serum is plasma without clotting factors, and blood plasma is the liquid component of blood containing clotting factors.
Solution
a
Whole blood: This is the blood directly sampled from the body without any components removed. It includes plasma, red blood cells, white blood cells, platelets, and other cellular components
b
Blood plasma: This is the liquid portion of whole blood that remains after the blood cells, platelets, and other cellular components are removed. Plasma contains water, salts, enzymes, antibodies, and other proteins, including clotting factors such as fibrinogen
c
Blood serum: Serum is similar to plasma but is the fluid that remains after the blood has clotted and the clotting factors have been removed. Serum therefore lacks fibrinogen and other clotting factors
Key Concept
The main difference between whole blood, blood serum, and blood plasma lies in the presence or absence of cellular components and clotting factors.
Explanation
Whole blood contains all components, plasma includes clotting factors but no cells, and serum is plasma without clotting factors.
