  1. Sponge # 2 • What are some of the ways pathogens enter the body? • Explain what happens when you get a mosquito bite.

  2. SKIN!!!!!!! • Cuts and wounds are entry points • Eyes • Nose • Ears • Mouth • Excretory Organs (lungs)

  3. Your body responds to pathogens in several different ways • Your skin may swell and itch • Your immune system attacks the pathogens that entered your skin

  4. KEY CONCEPTThe immune system has many responses to pathogens and foreign cells.

  5. extracellular space capillary wall white blood cell • Nonspecific responses are the same for every pathogen. • In inflammation, blood vessels become leaky. • white blood cells movetoward infection anddamaged tissue • characterized by swelling, redness, and pain

  6. Low fevers stimulate white blood cells to mature. • In fever, body temperature increases. • High fevers can cause seizure, brain damage, and even death.

  7. antigens virus • Antigens are surface proteins on pathogens. • Each pathogen has a different antigen. • Help the immune system identify a foreign cell or virus

  8. B cell T cell • memory cells- specialized T and B cells that provide acquired immunity because they “remember” an antigen that has previously invaded your body • Next time they come across the same pathogen they destroy it before you get sick

  9. The immune system rejects foreign tissues. • Tissue rejection occurs in organ or tissue transplants. • Tissue rejection is the result of an immune response. • immune system detects protein markers on the donor tissue • makes antibodies against the donor’s tissue
