Question

What are the functions performed by histamine in the body?

Answer 1

The functions of histamine are as follows:

• Histamine is a potent vasodilator.
• It contracts muscles in the gut and bronchi and relaxes other muscles like those in the walls of fine blood vessels.
• It is also responsible for congestion in the nose associated with the common cold and allergies.
• Histamine stimulates the release of pepsin and hydrochloric acid in the stomach.
