Coughing and sneezing are reflexes of the body
that prevent bacteria to further damage the organs inside the body. It helps in
keeping the airways clear and in healing. The two sources or passages of these
natural reflexes are the nose and the mouth.
<span>
Inside the nose, there are nasal hairs present to
filter the oxygen or air that we breathe in. These are called Cilia, these are
protective mechanisms of the body that trap dirt that cannot pass through the
respiratory system. Sneezing is a natural reflex that clears the nose passages
from obstructions that might affect the lungs. Coughing is also a natural
reflex that is generated by an irritation in the tonsils, this condition is
commonly viral. The tonsils are responsible for protecting the passage of dirty
air into the lungs.</span>
<h2>Intestinal Epithelial Cells (IEC)</h2>
Explanation:
- <em>Polarized intestinal epithelial cells (IEC),</em> as well as the resident microflora, provide a barrier that guards <em>against microbial invasion</em>
- The necessity for the <em>epithelium </em>to maintain an intact barrier between <em>lumen bacteria</em> and the lamina propria is exemplified by the consequences after the barrier function is altered
- Impairment of the barrier function of the <em>intestinal epithelium may be a predominant mechanism in the pathogenesis of inflammatory bowel disease (IBD)</em>
