Answer
(c) Lysozyme (d) Very acidic pH (b) Sebum, and fatty acids (a) Low pH, flushing action of urine (f) Mucociliary escalator (e) Phagocytes
Work Step by Step
The following are the innate defense mechanisms with their associated structure/body fluid:
Lysozyme- Tears and saliva
Very acidic pH- Stomach
Sebum, and fatty acids- Skin
Low pH, flushing action of urine- Urogenital tract
Mucociliary escalator- Bronchial tubes
Phagocytes- Lower respiratory tract
