ANATOMY & PHYSIOLOGY 241

Study of the Human Body

anatomy physiology
ANATOMY & PHYSIOLOGY
  • ANATOMY
    • structure
    • how form & structure relate to each other
  • PHYSIOLOGY
    • how anatomy functions
  • Structure determines Function
    • complementarity of structure & function
ways to study anatomy
WAYS TO STUDY ANATOMY
  • Microscopic
    • Cytology
        • Study of cells
    • Histology
        • Study of tissues
  • Gross
    • Surface
    • Regional
    • Systemic
    • Developmental
levels of organization1
LEVELS OF ORGANIZATION
  • Chemical or Molecular

Atomsmolecules

  • Cellular

basic unit of structure and function in living things

makes up organelles

  • Tissue Level

cells of similar structure & function working together to perform a specific activity4 basic types: connective, epithelial, muscle and nerve

levels of organization2
LEVELS OF ORGANIZATION
  • Organ Level

tissues working together to perform a specific activity

Examples - heart, brain, skin, etc.

  • Organ Systems Levelgroups of two or more tissues working together to perform a specific function11 organ systems - circulatory, digestive, endocrine, urinary, immune(lymphatic), integumentary, muscular, nervous, reproductive, respiratory & skeletal
  • Organism Levelentire living things that can carry out all basic life processes-usually made up of organ systems
    • An organism may be made of one cell
basic life processes
Basic Life Processes
  • Organisms share 6 basic life processes
  • 1. Metabolism
  • 2. Responsiveness
  • 3. Movement
  • 4. Differentiation
  • 5. Growth
  • 6. Reproduction
metabolism
Metabolism
  • sum of all chemical processes that take place in the body
  • Catabolism
    • larger macromolecules are broken down into smaller subunits or monomers
  • Anabolism
    • larger macromolecules are formed from smaller submits.
responsiveness
Responsiveness
  • ability to detect & respond to changes
differentiation
Differentiation
  • ability of cells to develop from an unspecialized cell into a specialized cell
growth
Growth
  • a way to increase in size
reproduction
Reproduction
  • making a whole new organism
  • Cells able to divide and make new cells for
  • Growth
  • replacement
homeostasis
Homeostasis
  • organ systems are interdependent
  • share same environment
  • composition effects all inhabitants
  • internal environment must be kept stable
  • maintaining stable internal environments-homeostasis
    • dynamic equilibrium
homeostasis1
Homeostasis
  • varies around a Set Point
    • average value for a variable
  • specific for each individual
    • determined by genetics
  • normal ranges for a species
    • temperature 36.7 – 37.2
homeostatic regulation
HOMEOSTATIC REGULATION
  • Autoregulation
    • cells, tissues, organs adjust automatically to environmental changes
  • Extrinsic Regulation
    • Nervous System
      • Fast
      • Short lasting
      • Crisis management
    • Endocrine System
      • Longer to react
      • Longer lasting
parts of homeostatic regulation
Parts of Homeostatic Regulation
  • Receptor
    • sensitive to environmental change or stimuli
  • Control or Integration Center
    • receives & processes information supplied by receptor
    • determines set point
  • Effector
    • cell or organ which responds to commands of control center
feedback loops
FEEDBACK LOOPS
  • Negative Feedback
    • output of system shuts off or reduces intensity of initiating stimulus
    • most often seen in the body
  • Positive Feedback
    • initial stimulus produces a response that exaggerates or enhances its effect
    • blood clotting & child birth
