Overproduction of these molecules is a major cause of inflammation in asthma and allergic rhinitis

Answer 21

Leukotrienes

Question 22

One important role of these cells is the removal of necrotic cellular debris in the lungs

Answer 22

Macrophage

Question 23

Share the “vacuum cleaner” (phagocytosis) function of neutrophils, but are much longer lived as they have an extra role

Answer 23

Monocytes

Question 24

Responsible for cell-mediated immunity

Answer 24
