The white blood cell labelled X primarily acts by:Question 5Answera.Coagulationb.Degranulationc.Antibody productiond.Phagocytosis

To determine the primary action of the white blood cell labelled X, we can briefly analyze each option:

1. Coagulation: This is primarily a function of platelets and not white blood cells.

2. Degranulation: This refers to the release of substances (like histamine) from the granules in certain white blood cells, especially mast cells and granulocytes.

3. Antibody production: This is the main function of B-cells, a type of white blood cell, wherein they produce antibodies to fight pathogens.

4. Phagocytosis: This is a process by which certain white blood cells, like macrophages and neutrophils, engulf and digest pathogens or debris.

Answer

The white blood cell labelled X primarily acts by: c. Antibody production.
