What is homeostasis? (3)

During healing periods, the body may experience strange and unusual symptoms (such as vomiting, diarrhea, etc.) which are good but oftentimes cause unnecessary worries on the part of the individual.

The body’s physical barriers and other first line defenses most often prevent microbes and other foreign matter from entering the body’s inner tissues… but not always.  Bacteria sometimes enter the deeper layers of the skin through a cut in the finger.  Viruses slip through the lining of the respiratory and digestive tracts, penetrating the lungs or intestines.  Such invading microorganisms usually encounter the full force of the immune system and are destroyed on the spot.

Amazing isn’t it?
