Med terms ch 6 presentation

  1. 1. Christina Wilbur<br />Prof. R Abdullah<br />Spring 2011<br />Lymphatic and Immune System Terms<br />
  2. 2. Phagocytosis<br />Process of engulfing and digesting bacteria and other foreign material (“phag/o” = eat, swallow) <br />Critical for the control of bacteria in the body<br />Phagocytes are attracted to the infected area via chemical signals from the damaged cell or the microorganism itself<br />Bacteria <br /> Phagocyte <br />
  3. 3. Phagocytosis<br />The phagocyte attaches to the bacteria through a variety of receptors <br />The bacteria is then engulfed by the phagocyte into a vacuole called phagosome<br />
  4. 4. Phagocytosis<br />Lysosomes inside the phagocyte release digestive enzymes that eat away and kill the bacteria<br />The digested contents are then removed from the phagocyte through exocytosis<br />
  5. 5. Antibody<br />Protective protein that is produced by the immune system when the body detects harmful substances <br />Each antibody is unique and protects the body against one specific type of antigen<br />Antibodies bind with the antigen to successfully remove it from the body<br />Antibody<br />
  6. 6. Antibody<br />Antibodies are part of the Humoral Immunity response which produces a type of WBC called B-cells <br />B-cells carry of the production of antibodies <br />Antibodies combine with Antigens located on the RBC to form the antigen-antibody complex<br />Prevent the foreign material from attacking healthy cells<br />Send signals and targets the object for phagocytosis<br />
  7. 7. Vaccination<br />Form of active acquired immunity <br />Patient is exposed to a modified or weakened version of the pathogen or virus <br />Vaccine still stimulates the immune response without causing the disease<br />The body is able to neutralize the modified version of the virus<br />If or when the patient is exposed to the actual virus, the body will be able to more quickly recognize and destroy it without symptoms. <br />
