Q.State the functions of the following in blood
a. Fibrinogen
b. Globulin
c. Neutrophils
d. Lymphocytes

a. Fibrinogen is a plasma protein required for the clotting (coagulation) of blood.

b. Globulins are plasma proteins chiefly involved in the body's defence mechanisms.

c. Neutrophils, the most abundant white blood cells, are phagocytic — they engulf and destroy foreign organisms entering the body. …

a. Fibrinogen. This plasma protein is required for the clotting (coagulation) of blood — it is the inactive precursor that is converted into the fibrin threads that form a clot.

b. Globulin. Globulins are chiefly part of the body's defence mechanisms among the plasma proteins.

c. Neutrophils. These are the most abundant white blood cells, making up about 60 to 65 per cent of the total. Along with monocytes, they are phagocytic — they engulf and destroy foreign organisms that enter the body. …

Method: Matching a Blood Component to Its Function

Use this approach for any "state the function of" question listing several blood components together.

Steps

Step 1: Sort each item into plasma protein or formed element

Fibrinogen and globulin are plasma proteins (dissolved in the liquid plasma); neutrophils and lymphocytes are formed elements, specifically types of white blood cell. This sorting alone predicts the category of function each will have.

Step 2: Recall the one signature function tied to each name

• Fibrinogen -- clotting (the precursor converted to fibrin).
• Globulin -- defence (broad immune/carrier role among plasma proteins).
• Neutrophils -- phagocytosis (engulfing foreign organisms). …
