Physiology of Basophils, Mast Cells, & Eosinophils

The video tutorial discusses various types of white blood cells, focusing on basophils, mast cells, and eosinophils. Basophils and mast cells have similar functions but differ in location, with basophils in the blood and mast cells in tissues. They release chemicals like histamine, heparin, prostaglandins, pyrogens, and chemotactic factors to create an environment conducive to immune defense. Eosinophils, another type of granulocyte, directly attack parasites by releasing cytotoxic chemicals. The video explains the roles of these cells and the chemicals they release in the immune response.
