Inmune system

Inmune system

What does it do?
1. ·Defect
  1. ·Deflect
    1. ·Destroy
What does it have?
1. ·Lymph nodes
  1. ·Lymph vessels
    1. ·Lymphocytes
      1. ·Blood marrow
        ·White blood cells
        ·Skin membrane
How does it work?
1. Innate defense system
  1. Internal defenses
    1. ·Phagocytes
      1. ·Antimicrobial proteins
        ·Attack cells
    2. ·Is the second line of defense·Fight with fever ·Reduces inflamation ·Reduces chemical signals ·Help attack invators
      1. PHAGOCYTES ·Eat like pacman
      2. NEUTROPHILS ·The most abundant type of your white blood cells ·Go away after eating a pathogen
      3. M,ACROPHAGES ·Big eater ·Use cytoplasmatic extensions ·Fix types ·Attack the ones that pass by ·Look for danger
      4. NATURAL KILLER CELLS ·Can kill your own cells if their are infected
  2. External barricate
    1. ·Skin mocus membrane
  3. Simple physical barriers
    1. Keep out all manner of malevolent microorganisms
    2. Protects: ·respiratory, ·digestive, ·urinary, ·reproductive systems, from the external world
  4. It uses an arsenal of physical and chemical barriers killer cells and even fever to keep you healthy
2. Adaptive defense system
Hhow they were to look for problems?
1. INFLAMATORY RESPONSE ·Internal fire alarm, that use:-redness -swelling -heat -pain
  1. ·By sending histaminemolecules
    1. ·Then, phagocytes are called lymphocites
2. LEUKOCYTOSIS ·Send chemicalsthat homing devices. ·And then the neutrophils arrive get into the vessels to get to work
