MICROANATOMY

Detailed explanation-1: -Basophils contain anticoagulant heparin, which prevents blood from clotting too quickly. They also contain the vasodilator histamine, which promotes blood flow to tissues. They can be found in unusually high numbers at sites of exoparasite infection, e.g., ticks.

Detailed explanation-2: -Basophils also release an enzyme called heparin that prevents blood from clotting too quickly. The granules of basophils hold both histamine and heparin. When a foreign organism enters your body, your basophils activate and release these enzymes to assist your immune system’s response to destroy the organism.

Detailed explanation-3: -So, the correct answer is ‘Basophils’.

Detailed explanation-4: -Basophils contain the anticoagulant heparin, which prevents blood from clotting too quickly, and the vasodilator histamine, which promotes blood flow to tissues.

Detailed explanation-5: -A type of immune cell that has granules (small particles) with enzymes that are released during allergic reactions and asthma. A basophil is a type of white blood cell and a type of granulocyte.
