Step 1: Function of fibroblasts.
Fibroblasts are connective tissue cells responsible for the secretion of fibres like collagen and elastin. Step 2: Function of mast cells.
Mast cells release histamine and heparin during inflammatory responses. Step 3: Function of macrophages.
Macrophages are phagocytic cells involved in engulfing pathogens and debris. Step 4: Function of adipocytes.
Adipocytes store fat and help in energy reserve.
