MBIO 1010 Lecture Notes - Lecture 21: Mast Cell, Granulocyte, Innate Immune System
Document Summary
Cells that circulate in the blood and lymph, and reside in lymphoid organs . Involved in both branches of the immune response (innate and adaptive) . Granulocytes: cytoplasm contains granules filled with reactive chemicals. Signal other components of immunity: 3 types. They create proteins that get sent to get tell the parts of the body to come to the certain area of the body (signal) for help. Basophils and mast cells granules stain with basic dyes. Circulate in blood (basophils) or reside in mucosal tissue (mast cells) . Inside the granules contain histamine= vasodilation and is a respirator inhibitor. They limit inflammation in the body histamine is helpful in normal blood vessel properties and digestion. Can leave the blood and enter tissues in areas of inflammation . , h2o2, oh : destroy parasite from the outside. Spit digestive enzymes on the organism and you break it down extracellular and then the extra pieces is used for our own body.
