Basophils Release Heparin,which Helps the Blood Clot

Question

Basophils release heparin,which helps the blood clot.

Accepted Answer

Basophils release histamine and other inflammatory substances, not heparin. Heparin is actually released by mast cells, which are similar to basophils but found in tissues rather than circulating in the bloodstream. Heparin helps to prevent blood clots, not promote them.
