IMMUNE SYSTEM

• IMMUNE SYSTEM

  • complex network of organs, cells, proteins
  • defends body against infection
  • protects body’s own cells
  • keeps record of every germ (microbe) it has ever defeated
  • recognize and destroy microbe quickly if it enters the body again
• ABNORMALITIES OF THE IMMUNE SYSTEM IT CAN LEAD TO:

  • allergic diseases
  • immunodeficiencies
  • autoimmune disorders
• TWO TYPES OF RESPONSES

  • Innate immunity
  • Adaptive immunity
• rapid response (hours)


  INNATE IMMUNITY
• quick reaction when bad guys shows up


  INNATE IMMUNITY
• non specific response to foreign molecules


  INNATE IMMUNITY
• Doesn't Care Who the Bad Guy Is, it just knows they’re bad

  INNATE IMMUNITY
• response fixed

  INNATE IMMUNITY
• Always Acts the Same Way, It fights bad guys in the same way every time.

  INNATE IMMUNITY
• no immunological memory


  INNATE IMMUNITY
• Forgets Easily; if bad guys come back, it's like meeting them for the first time again.(TYPE OF RESPONSE)

  no immunological memory (INNATE IMMUNITY)
• delayed response

  ADAPTIVE IMMUNITY
• Knows Who the Bad Guy Is, It fights only that bad guy(TYPE OF RESPONSE)

  highly specific response to antigen (ADAPTIVE IMMUNITY)
• Always Acts the Same Way, It fights bad guys in the same way every time.(TYPE OF RESPONSE)

  response fixed (INNATE IMMUNITY)
• Forgets Easily; if bad guys come back, it's like meeting them for the first time again.(TYPE OF RESPONSE)

  No immunological memory (INNATE IMMUNITY)
• response (days)


  ADAPTIVE IMMUNITY
• highly specific response to antigen


  ADAPTIVE IMMUNITY
• response adaptive (changes over time)


  ADAPTIVE IMMUNITY
• immunological memory(TYPE OF RESPONSE)


  ADAPTIVE IMMUNITY
• Never Forgets a Bad Guy(TYPE OF RESPONSE)

  immunological memory (ADAPTIVE IMMUNITY)
• Each time it fights, it learns new tricks to beat the bad guy.(TYPE OF RESPONSE)

  response adaptive (changes over time)(ADAPTIVE IMMUNITY)
• Knows Who the Bad Guy Is, It fights only that bad guy.(TYPE OF RESPONSE)

  highly specific response to antigen (ADAPTIVE IMMUNITY)
• innate immunity acts fast but forgets easily, while adaptive immunity takes longer but remembers forever and learns from each fight. Both work together to keep us healthy.
• first line of defense(TYPE OF RESPONSE)


  INNATE IMMUNITY
• ADAPTIVE IMMUNITY (Hours of response)

  >96 HOURS
• INNATE IMMUNITY (Hours of response)

  0-96 HOURS
• CELLS UNDER INNATE IMMUNITY (7)

  • natural killer cells
  • macrophages
  • neutrophils
  • dendritic cells
  • mast cells
  • basophils
  • eosinophils
• CELLS UNDER ADAPTIVE IMMUNITY (2)

  • T LYMPHOCYTES
  • B LYMPHOCYTES
• ANTIGEN DEPENDENCY OF INNATE IMMUNITY

  INDEPENDENT
• ANTIGEN DEPENDENCY OF ADAPTIVE IMMUNITY

  DEPENDENT
• EXAMPLES OF INNATE IMMUNITY (8)

  • skin
  • hair
  • cough
  • mucous membranes
  • phagocytes
  • granulocytes
  • fever
  • sneezing
• EXAMPLES OF ADAPTIVE IMMUNITY (5)

  • pus
  • swelling
  • redness
  • pain
  • T and B lymphocyte response
• MAIN COMPONENTS OF BLOOD (4)

  • Plasma
  • Red blood cell (erythrocyte)
  • White blood cell (leukocytes)
  • Platelets (thrombocytes)
• Red blood cell (_)

• White blood cell (_)

  leukocytes
• Platelets (_)

  thrombocytes
• PLASMA (_)

  dextrose
• carries water, salts, and enzymes


  PLASMA
• take nutrients, hormones, proteins to parts of body that needs it


  PLASMA
• cells put their waste products into _
