Answer 1

1. neutrophil- answer is

   5. elevated in response to bacterial infection..... As neutrophil is also called polymorphonuclear cell ... It is phagocytic in nature and destroys opsonised bacteria... Also, Antimicrobial action of neutrophils is more potent than that of macrophages, and they have several microbicidal methods.Like myeloperoxidase(MPO).

2. basophil- answer- mainly elevated in response to allergens...

   Mediating allergic reactions: In allergic reactions, the immune system is exposed to an allergen. Basophils release histamine during allergic reactions. Basophils are also thought to play a role in causing the body to produce the antibody called immunoglobulin E (IgE).

   This antibody then binds to basophils and a similar type of cell called mast cells. These cells release substances such as histamines and serotonin. They mediate the inflammatory response in the area of your body that was exposed to the allergen.....

3. Eosinophil- answer - elevated in reponse to larger parasites& allergens.....

4. Macrophage- answer-

   . phagocytizes stuff

   . elevated in response to bacterial infection... Commonly seen in large number in chronic inflammatory conditiin like Granulomatous diseases like TB, cat scratch disease etc..

5. Platelet- answer- . elevated in response to bacterial infection as

platelet and platelet-derived mediator interactions with the innate and acquired arms of the immune system and platelet-vessel wall interactions that drive inflammatory disease..Platelets interact with white blood cells and vascular endothelial cells both directly by contact-dependent mechanisms and indirectly through secreted immune mediator-driven mechanisms....... Platelet interactions with inflammatory cells may mediate proinflammatory outcomes, but these interactions have likely evolved to be beneficial in limiting infection. For example, with a breach in the skin there is exposure to pathogens, and by combining thrombotic and immune recruitment functions, platelets may help focus hemostasis and immune responses against potential infectious agents to prevent pathogen invasion.
