3. ORGAN SYSTEMS OVERVIEW
 Levels of organisation  Organ system level
 Atoms  Group of organs that have close
 Molecules
interactions.
 Interact with other systems also.
 Cells
 Tissue
 Organ  Something that affects a
 Organ System system will ultimately affect
 Organism
each of the systems
components.
 There are 11 interdependent,

4. HOMEOSTASIS
 Homeo – unchanging
 Statis – standing
 “The body’s automatic tendency to maintain a relatively constant
internal environment within a dynamic state of equilibrium.”
 Internal conditions change/vary (oscilate) within narrow limits.
 Two mechanisms
 Autoregulation – when a tissue, organ or organ system responds
automatically
 Extrinsic regulation – when response results from the action of one of the two
organ systems that control or adjust the function of many other systems
simultaneously
