    • Inspection
    • Looking at the bodies appearance
  1. Palpation
    Feeling a structure with the hands, such as popping a swollen lymph node or taking a pulse
  2. Auscultation
    Listening to the natural sounds made by the body
  3. Percussion
    The examiner tap from the body feels for abnormal resistance and listens for signs of abnormalities
  4. Dissection
    Cutting And separation of tissues to revealthe relationship
  5. Cadaver
    Dissecting a dead human body
  6. Comparative anatomy
    Study of more than one species in order to examine structural similarities
  7. Physiology
    The study of function
  8. Anatomy
    the study of structure
  9. Evolution
    Change in the genetic composition of a population of organisms
  10. Organism
    A single complete individual, the baby
  11. Organ system
    a group of organs with a unique Collective function. example the circulation respiratory or digestive
  12. Organ
    A structure composed of two or more tissue types at work together to carry out a particular function examples skin pancreas
  13. tissue
    • Mass of similar cells and cell products that forms a discrete region of an organ and performs a specific function
    • 4 classes - epithelial, connective, nervous, and muscular tissue
  14. Cell
    • Are the smallest units of an organism that carry out all of the basic functions of life.
    • Most cells have one nucleus an organelle that contains its Dna
  15. Organelle
    Microscopic doctors in a cell that carry out its individual functions example mitochondria, centrioles, and lysosomes
  16. Molecules
    Composed of two atoms
  17. Organization
  18. Cellular composition
  19. Metabolism
    • Is the sum of all this internal chemical change
    • Consists of two classes of reaction anabolism and catabolism
  20. Anabolism
    Molecules are synthesized together
  21. Catabolism
    • Molecules are broken down into simpler ones
    • examples protein digestion
  22. Excretion
    The separation of waste from tissues and their elimination from the body
  23. Responsiveness
    The ability of organisms to sensr and react to stimuli
  24. Homeostasis
    • Keeping internal conditions able
    • Dynamic equilibrium
  25. Development
    • Any change in former function over the lifetime of the organism involves two major processes differentiation changing cells into cells are committed to a particular task
    • Growth an increase in size
  26. Reproduction
    Passing the genes over
  27. Evolution
    Population changing as a whole their genetics change
  28. Negative feedback
    • A process which the body senses a change and activates mechanisms or reverses it.
    • Example thermo stat
    • Vasoconstriction when cold (shivering)
    • Vasodilation when hot (sweating)
  29. Homiel static control of blood pressure
    • 3 components
    • Receptor- this is a change in the body
    • Integrating center- control center
    • Effector- cell organ carries out the action
  30. Positive feedback
    Producing rapid change example stimulating contractions
