multiple choice question
heparin is secreted by which of the following?

basophils

heart cells

monocytes

platelets

Explanation:

Heparin is a substance related to blood clotting and immune response. Basophils, a type of white blood cell, secrete heparin (along with histamine) which helps in preventing blood clotting and is involved in allergic reactions. Heart cells don't secrete heparin. Monocytes are involved in phagocytosis and immune response but not heparin secretion. Platelets are involved in blood clotting but don't secrete heparin.

Answer:

A. Basophils
