DANCE 3 Lecture Notes - Lecture 15: Gastroenteritis, Blood Pressure, Blood Test
Document Summary
Don"t worry about differences between cold and flu. Won"t be really tested on defenses in innate. Medical science has created two systems for augmenting the human system: antibiotics. Antibiotics help destroy bacteria but not viruses. Antibiotics work in one of several ways: slowing bacteria reproduction, interfering with bacterial cell wall. Antibiotics do not weaken our immune system. Humans do not become immune to antibiotics. Bacteria that resist antibiotics and are not completely destroyed may multiply, producing more bacteria. Variolation: the deliberate inoculation of people with secretions from smallpox (variola) sores, by inhaling the dried secretions or rubbing them on broken skin. Modern vaccines are created from killed bacteria or viruses, or fragments of proteins from these microbes. The proteins are recognized as antigens by our immune systems. Memory t-cells and b-cells remain ready to fight off the illness if it is encountered again.
