A) Cell cytoplasm
B) Interstitial fluid
C) Gastric secretions
D) Cerebrospinal fluid
Ans: C
Feedback:
Chemical barriers, such as mucus, acidic gastric secretions, enzymes in tears and saliva, and substances in sebaceous and sweat secretions, act in a nonspecific way to destroy invading bacteria and fungi. Not all body fluids are chemical barriers, however. Cell cytoplasm, interstitial fluid, and CSF are not normally categorized as chemical barriers to infection.
