Mast cells throughout the bronchi releasing materials such as histamine and leukotrienes that cause: smooth muscle contraction, and an increase in mucus formation, and the transfer of certain white blood cells into the bronchi. Mastocyte removing such materials as a response to something that they know as a foreign body (allergens) such as pollen, fine dust contained in the house, or animal dander.
