• Refers to the ability of the body to distinguish self from nonself:

  immunity
• Immunoglobulin proteins that can bind to antigens are known as:

  antibodies
• Which of the following describes the role of immunity in the body?

  All of the above
• These are antigens that are too small such that they need to be bound to a host macro molecule in order to generate and immune response:

  Hapten
• These molecules are also known as antigenic determinants:

  Epitope
• During the process of antigen presentation in the generation of an immune response, the epitope will bind to:

  MHC protein
• The first step that occurs in antigen processing is:

  Phagocytosis of the antigen
• Which of the following DOES NOT describe Natural Immunity?

  Involves production of specific antibodies against an invading antigen.
• The skin as a physical barrier is an example of:

  natural immunity
• Production of Immunoglobulin G is an example of:

  adpative immunity
• Production of memory cells as a result of vaccination

  artificial active immunity
• Temporary immunity coming from the injection of commercially available immunoglobulins:

  artificial passive immunity
• Temporary immunity that a fetus acquires from its mother:

  natural passive immunity
• You got sick for 3 days and developed punctate-like rashes all over your body. The Doctor said that you have to keep away from other people because you might spread the disease. After 3 months, you notice that a classmate sitting beside you had the same symptoms that you had before. You expected to contract the disease but you remained unaffected. What kind of immunity do you have?

  natural active immunity
• Which of the following will give you Natural Active Immunity?

  Exposure to the disease
• Which of the following will give you Artificial Passive Immunity?

  injection of immunoglobins
• Precursosrs of tissue macrophages

  monocytes
• These cells increase in the presence of parasitic infestation and in hypersensitivity:

  Eosinophils
• These cells are also known as the scavenger WBC and contain potent bactericidal enzymes:

  Neutrophils
• You were given 2 shots of live attenuated COVID 19 vaccine, 4 weeks apart. What kind of immunity will you develop?

  artificial active immunity
• Eosinophils

  Natural Immunity
• Mast Cells


  Natural
• Cytokines

  Natural
• Immunoglobulins


  Adaptive
• Plasma Cells


  Natural
• Destroy Bacterial Cell Wall

  Lysozyme
• Responsible for opsonization, inflammation and lysis.

  Complement System
• Produced in the liver and facilitates phagocytosis

  C-reactive protein
• Stimulates proliferation and maturation of lymphocytes

  Interleukins
• Signaling Proteins


  Interferon
• Products of Arachidonic Acid metabolism:

  Prostaglandins
• This molecule of natural immunity attack tumors by damaging their blood vessels:

  Tumor Necrosis Factor
• Precursors of tissue macrophages

  Monocytes
• These cells increase in the presence of parasitic infestation

  Eosinophils
• These cells are also known as the scavenger WBC and contain potent bactericidal enzymes:


  neutrophils
• Antibody production 


  Humoral immunity
• This type of immunity requires contact of the antigen with T lymphocytes:

  cell mediated immunity
• Maturation of CD4 T cells require presentation of the antigen to MHC class:

  II
• Antibodies mask pathogenic region of antigen


  recognition
• Antigen binds to IgM or IgG, antibody changes shape, initiates binding


  Neutralization
