Solution

The correct option is C Mast cells
  • The abundant cell in CT prepare is fibroblast
  • Adipocytes are cells - store lipids as droplets in the cytoplasm
  • Mesenchymal cell - multipotent adult stem cell.
  • Macrophage cell - Large cell derived from a monocyte which inters connective tissue from blood vessels.
These are an essential component of the immune system, which is the body's defense against potential pathogens and degraded host cells.
Macrophages when stimulated release cytokines, which is used in chemical messengers.
  • Mast cell:- has cytoplasmic granules that contain histamine and heparin.
when damaged, mast cell release histamine an inflammatory mediator, tat causes vasodilation & increases blood flow at the site of injury or infection. So option C is correct.
