- - - - Heparin is an anticoagulant
      - Histamine increases capillary permeability
    - - Perforin-creates a hole in a cell
      - Granzymes-enzymes that travel through the hole that make the cell to burst
    - - Signs: redness(blood is red), Heat (blood gives off heat), Swelling (more fluid means more volume), Pain( kinins, or fluid pinching nerves)
      - Has 4 steps:
        
        tissue is damaged, cause chemicals to release
        
        Chemicals make WBC's stick together
        
        Once they stick, they squeeze through capillary walls, then go to the site of infection
        
        Once WBC's and compliment and plasma fill the site, residue is taken away by lymph, taken to vessels, big circle
    - - Interferon-makes cells resistant to viral reduction, antiviral
      - Compliment System is a group of proteins that act to help the 2nd line of defense
      - CRP-(from the liver) binds to pathogen to mark it for destruction by macrophages
