A client asks, "What do these basophils and mast cells do in the body?" The health care provider responds that they:
A) Are involved when you have an allergic reaction
B) Stiffen your cell membranes so bacteria cannot enter
C) Help your body to eliminate parasitic infections
D) Help your body produce immune responses
Ans: A
Feedback:
The basophil, which is a blood cell, is related to the connective tissue mast cell that contains similar granules. Both the basophils and mast cells are thought to be involved in allergic and hypersensitivity reactions. These cells do not stiffen the cell membranes. In parasitic infections, the eosinophils use surface markers to attach themselves to the parasite and then release hydrolytic enzymes that kill it. Lymphocytes migrate through the peripheral lymphoid organs, where they recognize antigens and participate in immune responses.
