Mast cells of connective tissue contain -

  1. Heparin and calcitonin
  2. Heparin and histamine
  3. Vasopressin and relaxin
  4. Serotonin and melanin

Answer

(2) Heparin and histamine

Solution

As per NCERT, mast cells of areolar connective tissue secrete histamine, heparin and serotonin.

⇒ Calcitonin (thyroid), vasopressin (posterior pituitary), relaxin (ovary/placenta) and melanin (pigment) are not mast-cell products.

∴ Mast cells contain heparin and histamine.

Answer: (2)
