Question

Which of the following is a part of the body's innate defences?
A)Lysozyme.
B)Mucopolysaccharide.
C)Sweat.
D)Fatty acid.
E)All of the above.

Accepted Answer

All of the choices listed are part of the body's innate defenses. Lysozyme, found in tears and saliva, breaks down bacterial cell walls. Mucopolysaccharides, present in mucus, can trap pathogens. Sweat can limit bacterial growth on the skin through its acidic pH. Fatty acids in the skin also create an environment that is inhospitable to many microorganisms.
