Answer 2

Answer:

d) Basophil is the right answer.

Explanation:

• Basophils are  cells of the immune system that do not perform phagocytosis.
• Phagocytes are cells that protect the body by ingesting  harmful foreign substances and bacteria.
• White blood cells swallow and absorb waste products, harmful microorganisms, or other foreign substances in the bloodstream and tissues.
• However, basophils account for less than 0.5% of human peripheral blood leukocytes and have do not possess phagocytosis activity.
• Basophils contain the anticoagulant heparin, which prevents blood from clotting too quickly.
• They also contain vasodilator histamine, which increases blood flow to tissues.
• Macrophage, Neutrophil, Eosinophil are all cells of immune system that perform phagocytosis.
• Therefore, the right answer from the following is Basophil.
