Question

Which Type Of White Blood Cells Are Concerned With The Release Of Histamine And The Natural Anticoagulant Heparin?

• A. Eosinophils
• B. Basophils
• C. Neutrophils
• D. Monocytes

Answer 1

The correct option is B

Basophils

The correct option is b.

Explanation of correct answer:

1. The function of basophils is similar to that of mast cells.
2. Hence, both these cells comprise histamine, heparin and serotonin.
3. Histamines are released in response to allergens such as food or dust, and heparins are anticoagulants that prevent blood clotting.

Explanation of incorrect answers:
Option a:

1. Eosinophils primarily deal with parasitic infections.
2. They are also the predominant inflammatory cells in allergic reactions.

Option c:

1. Neutrophils defend against bacterial or fungal infection and other very small inflammatory processes.
2. They are usually the first responders to microbial infection.
3. Their activity and death in large numbers from degranulation forms purulent necrosis (pus).
4. Option d:
   
   3Basophils are chiefly responsible for short-term inflammatory response (particularly from allergy or irritation) by releasing the chemical histamine, which causes the vasodilation that occurs with inflammation.
