- - - - Human immunodeficiency virus
      - Lives in body fluids of infected people
      - transmitted through the sharing of body fluids (sex, kissing, blood contact, etc)
      - Destroys helper T-lymphocytes
      - replicates faster than the body can destroy
      - No cure
    - - A condition that is a result of HIV
      - Acquired immunodeficiency syndrome
      - Considered AIDS when T-lymphocyte count drops below 200 cells per cubic millimeter
      - Also considered AIDS when a person develops and opportunistic infection or illness
  - - - Become macrophages and engulf
      - Fight parasitic infections
      - make up to 2%-8% of leukocytes in blood
    - - Allergies
      - fight parasitic worms
      - Make up 1%-4% of leukocytes in the blood
    - - Figth viral infections
      - used in specific immunity
      - make up 20%-40% of leukocytes in blood
    - - Allergies
      - release histamine and heparin
      - make up <1% of leukocytes in the blood
    - - Fight bacterial infection
      - make up 55%-70% of Leukocytes in blood
  - - - form leukocytes
    - - Tonsils
      - Lymph vessels
      - Spleen
      - Lymph nodes
      - Adenoids
  - - - Need a host in order to survive
      - Caused by entering host and multiplying within the hosts healthy cells
      - Viruses are not considered "alive"
      - antibiotics don't work for viral infections
      - Treatment methods typically involve immune system boosting remedies and symptom targeting medication
    - - single, but complex cell
      - can survive on its own inside or outside the body
      - Is considered "alive"
      - Treated with antibiotics for serious becterial infections
  - - - Prevent entry of foreign substances
      - Skin and mucosal membranes
      - Nonspecific internal defenses

        Complement
    - - lymphocytes are activated to replicate and respond when stimulated by a specific antigen
        
        T-lymphocytes
        
        B-lymphocytes
        
        Plasma cells
  - - - normal process of viral reproduction
      - cells are broken open and destroyed after replication of the virion
    - - viral reproduction involving the fusion of the nucleic acid of a bacteriophage with that of a host
      - does not result in immediate lysing of the host cell
      - viral genome comes in and integrates itself with the host DNA an replicates with it harmlessly
      - may cause cell to be established as a plasmid
      - remains dormant until nutrients run low then activates
- - - - AIDS due to the onset of symptoms and drop of T-lymphocyte count
      - Time with HIV has whittled down the immune system of the patient
