Question

During inflammation,which of the following is secreted by connective tissue?

• A. Serotonin
• B. Heparin
• C. Glucagon
• D. Histamine

Answer 1

The correct option is D Histamine

Histamine is an organic nitrogenous compound involved in the inflammatory response and has a central role as a mediator of itching. Histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine is stored in cytoplasmic granules along with other amines and rapidly released upon triggering with a variety of stimuli. It causes the contraction of smooth muscle, dilation of blood vessels etc..

So, the correct answer is 'Histamine'.
