The flashcards below were created by user ht2lvu on FreezingBlue Flashcards. What would you like to do?


  1. function
    barrier
  2. function as barrier
    • keeps h2o in
    • prevents entrance of foreigners
    • makes vitamin D
    • prevents DNA damage from UV radiation
    • prevents the spread of invaders once inside
    • sensory: detects conditions on/around body
    • temperature regulation
    • excretion
  3. steps of inflamatorys
    • broken cell releases histamine
    • other cells swell up
    • sphincter entering blood vessel opens & end closes
    • histamine trail is released
  4. h2o enters for swelling
    • seals hole
    • prevents spreading of invader
  5. blood vessel entering area to swell
    • sphincter opens
    • brings lots of white blood cells to area to kill
    • suger & oxygen for energy
  6. sphincter end closes
    • prevents spread of invaders
    • slows blood down so nutrients & white blood cells can enter wound area
  7. histamine trail
    • white blood cells follow trail
    • movement is efficient by histamine
    • damage to cells
    • allergens
  8. symptoms of over heating
    • red
    • sweat
    • stop sweating
    • faint
    • throw up
    • mixed temperature response
  9. steps of cooling body down
    • 1. hot blood stimulates hypothalamus
    • 2. nerve impulse is released from hypothalamus
    • 3. capillary in blood vessel gets bigger & lets out more heat
    • 4. sweat gland releases water from sweat gland & sweat is evaporated into hair causing cooling effect
    • 5. cooler blood enters the brain
  10. danger of overheating
    breaks down all proteins & enzymes --> no chemical reaction --> death
  11. cause of fever
    • parasites
    • one celled destroys enzymes in host & infector
    • loss to you is nothing compared to benefit
  12. symptoms of cold
    • shivering
    • muscle tense
    • pale blue
    • chicken skin=hairs stand up
    • lips get blue
  13. steps of getting cold
    • blood vessel shrinks
    • white fatty tissue becomes visible
    • arrector pilimuscle makes hairs stand up (vestigial)
  14. healing of superficial wounds
    • basale cells migrate to opening then multiply causing skin to form (mitosis)
    • changed keratinization & multiplying increases
    • scar tissue is less flexible & thincker
  15. healing of deep wounds
    • plugging
    • bleeding
  16. healing of deep wounds:plugging
    • 1. cells cut open --> chemicals for healing
    • 2. basale cells migrate --> multiply & fill inside (deep) to outside (superficial)
  17. healing of deep wounds: bleeding
    • 1. blood leaves blood vessel
    • 2. chemical reactions occur, platelets get stickier & fibers from two trapped blood cells- clots (himatoma)
    • 3. macrophages & neurothils- migrate out & digest fibers --> digest red blood cell
    • --biliverdin: black
    • -- WBC digests biliverdin: yellow
    • -- WBC digests the rest & biliverdin goes to liver
