Inflammation reaction is brought about by

  • A.Plasma cells
  • B.Mast cells
  • C.Macrophages
  • D.Adipose cells

Answer: B

Correct answer: Mast cells

Mast cells sit in the tissues, especially at surfaces that meet the outside world, packed with granules of histamine and other mediators. When triggered they degranulate, dilating local vessels and making them leaky - the redness, heat and swelling of inflammation. Macrophages contribute cytokines, but the immediate reaction is the mast cell’s.
