  1. gross anatomy
    • large structures
    • ex. regional, systemic
  2. microscopic anatomy
    • very small structures
    • viewed with microscope
    • ex. cytology, histology
  3. developmental anatomy
    • structural changes that occur throughout life span
    • ex. embryology
  4. levels of structural organization
    • atoms
    • cells
    • tissues
    • organs
    • systems
    • organisms
  5. integumentary
    • skin
    • protects deeper tissue from injury
    • synthesizes vitamin D
    • location of cutaneous nerve receptors
  6. skeletal
    • protects and supports organs
    • muscle attachment place
    • site of blood cell formation
    • stores minerals
  7. muscular
    • muscles, tendons, ligaments
    • allows locomotion
    • maintains posture
    • produces heat (exothermic)
  8. nervous
    • brain, nerves, spinal cord
    • respons to internal and external change
    • activates muscles and glands
  9. endocrine
    • glands
    • secretes regulatory hormones (growth, reproduction, metabolism)
  10. cardiovascular
    • transports materials in body via blood pumped in heart
    • -oxygen, carbon dioxide, nutrients, waste
  11. lymphatic
    • ducts, lymph nodes, vessels
    • returns fluids to blood vessles
    • disposes of debris
    • immunity
  12. respiratory
    • keeps blood supplied with oxygen
    • removes carbon dioxide
  13. digestive
    • breaks down food
    • allows for nutrient absorption into blood
    • eliminates indigestible material
  14. urinary
    • eliminates nitrogenous wastes
    • maintains acid-base ballance
    • regulates water and electrolytes
  15. survival needs
    • nutrients
    • oxygen
    • reproduction
    • growth
    • water
    • stable body temp
    • stable atmospheric pressure
  16. 2 components of homeostasis
    • receptor
    • control center
    • effector
  17. negative feedback
    • most control mechanisms in body
    • shuts off original stimulus; reduces intensity
    • shiver in order to decrease cold stimulus
  18. positive feedback
    • increases original stimulus to push variable farther
    • blood clotting and birth of baby
