IMMUNOLOGY

Detailed explanation-1: -Phagocytic cells consist of granulocytes (i.e., neutrophils, eosinophils, basophils, and mast cells), monocytes/macrophages, and dendritic cells. These cells participate in not only the phagocytosis but also the inflammatory process.

Detailed explanation-2: -Innate Immunity Many of the cells in the innate immune system (such as dendritic cells, macrophages, mast cells, neutrophils, basophils and eosinophils) produce cytokines or interact with other cells directly in order to activate the adaptive immune system.

Detailed explanation-3: -A mast cell (also known as a mastocyte or a labrocyte) is a resident cell of connective tissue that contains many granules rich in histamine and heparin. Specifically, it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems.

Detailed explanation-4: -Mast cells are a type of white blood cell that is found in tissues and organs. They are involved in allergic reactions, inflammatory responses, and other functions.
