Monocytes and lymphocytes

Question 9

High neutrophil

Answer 9

Bacterial and fungal infections

Question 10

Eosinophils

Answer 10

Parasitic infections and severe allergies

Question 11

Basophils

Answer 11

Allergic response

Question 12

Monocytes

Answer 12

Viral pathogens

Question 13

Lymphocytes

Answer 13

Adaptive immunity, viral infections

Question 14

Nonspecific response

Answer 14

Neutrophils and eosinophils destroy invaders via phagocytosis, apoptosis of neutrophils and release of peptidases forming pus

Question 15

Specific response

Answer 15

Lymphocytes recruited, B cells from bone marrow get stimulated by antigens to become plasma cells that secrete antibodies, T cells from thymus do cell-mediated immunity requiring cell-cell contact
