  • When the T cell finds the pathogen , what does it do? It enters the pathogen and releases cytotoxins into it and kills it OR it engulfs the pathogen
    Releases cytotoxins into the pathogen
  • What sticks to the wound that creates a mesh like structure to hold the clot? The fibrin OR the platelet
    Fibrin
  • T cells play a critical role in fighting only bacteria. True OR false
    False
  • In the lymph node the T cells can move in 2 directions. Some T cells move to the problem site. What do some of the T cells do?
    They stay as memory cells in the lymph node
  • During the inflammation stage damaged cells are removed. True OR false
    True
  • Name a cell that arrives as the first line of defense when a pathogen breaks through the skin. A macrophage OR a neutrophil
    Macrophage
  • What does a macrophage have that gives it the ability to kill a pathogen? It has enzymes in its cytoplasm OR it has a chemical in its cytoplasm
    Enzymes
  • How do the neutrophils destroy pathogens ? They release toxins OR they engulf the pathogen
    Release toxins
  • What are some of the first line defenses of the human body?
    Skin, mucus, cilia, fever, inflammation
  • Where do T cells come from in the body? From the bone marrow OR from the liver
    Bone Marrow
  • What is the name of the cell that comes to the wound to cause clotting? Neutrophil OR platelet
    Platelet
  • What does a macrophage do? It destroys the pathogen OR it copies the pathogen
    Destroys the pathogen
  • Does an antigen trigger an immune response in the body? Yes OR no
    Yes
  • The dendritic cell copies the recipe of the pathogen to pass on to the T cell. True OR false
    True
  • What are cilia in the nose and airway passages for? They remove dust particles/pathogens in mucus OR they trigger the immune system
    Collect dust/pathogens in the mucus
  • What does collagen do to the wound area? It strengthens it OR it changes the function of the cells
    Strengthens the tissue
  • Which cell is activated in the lymph node to attack the pathogen? The T cell OR the macrophage
    T cell
  • What is the first process called when the skin is broken? Hemostasis OR Inflammation
    Hemostasis
  • Why does swelling at the wound occur? It creates space for the cells to work OR it is that there is more water present
    Both
  • What is epithelialization? Is it when new cells grow OR when old cells are destroyed
    New cells grow
  • Where do immune cells live? In the spine OR in the lymph nodes
    Lymph nodes
