A) TRUE B) FALSE
Answer & Explanation Answer: B) FALSE

Explanation:

FALSE. Basophils number will not be increased when parasitic invasion occurs.


 


Basophils are a type of white blood cell. Although they're produced in the bone marrow, they're found in many tissues throughout your body. They're part of your immune system and play a role in its proper function.


 


Basophils appear in many specific kinds of inflammatory reactions, particularly those that cause allergic symptoms. If your basophil level is low, it may be due to a severe allergic reaction.


 


Basophils contain anticoagulant heparin, which prevents blood from clotting too quickly. They also contain the vasodilator histamine, which promotes blood flow to tissues.
