question 12 of 20
what is histamine, a mediator that supports the inflammatory process in asthma, secreted by?
lymphocytes
mast cells
neutrophils
eosinophils

Explanation:

In the context of asthma and the inflammatory process, histamine is a key mediator. Mast cells are known to secrete histamine, especially during allergic or inflammatory responses like those seen in asthma. Lymphocytes are involved in immune responses but not primary histamine secretion here. Neutrophils are part of the innate immune response and fight infections, not major histamine secretors. Eosinophils are involved in allergic reactions and parasitic infections but are not the main source of histamine in this context.

Answer:

B. Mast cells
