I read that opening in our face like nose and eyes are one which get us infected with numerous communicable diseases like cold , flu ebola etc. Both these organs have preventive mechanism like nose hairs, eye lash , etc. Which one of eye and nose does protect human better from airborne virus and bacteria?
Between the eyes and nose, which offers better immune protection
Neither. Both are mucous membranes lined by epithelial cells. Each is their own niche (and the nose has a number of sub-niches), with particular receptors, environmental factors, and immune factors that interact with pathogen factors. The interaction between the two produces the tissue tropism of a particular pathogen. Each is colonized with many commensal microbes, with some overlap (see Murray Medical Microbiology Ch 7 and this study of the eye). As far as "airborne" transmission, vs. inoculation by physical contact, the nose and nasopharynx are important structures in respiration. The eye is not.
