Anatomical Imaging
2 Approaches to Anatomy
Systematic and Regional Anatomy
Surface Anatomy
Study of body by systems
Regional Anatomy
Study of the organization of body by areas
Organization of Human Body
Chemical, cell, tissue, organ, organ system, Organism
Atoms interact and combine into molecules
Chemical Level
Basic structural and functional unit of organism
Cell Level
Group of similar Cells
Tissue Level
Two or more tissue types combining to perform common
Organ Level
Group of organs that together perform common functions
Organ System Levels
Any living thing considered as a whole
Organism Level
6 Characteristics of life
Organization, Metabolism, Responsiveness, Growth, Development, Reproduction
Organization
Specific interactions among parts of organisms and how they interact to perform specific functions
Ability to use energy to perform other vital functions
Metabolism
Responsiveness
Ability to sense external/internal changes in the environment and adapt
Increase in size of cells
Growth
Development
Changes an organism undergoes; Beginning in fertilization and ending in death.
Differentiation
Changes in cell structure and function; Immature state to mature specialized state.
Formation of new cells and organisms; prevents extinction of species
Reproduction
Maintenance of a relatively constant environment within the body
Homeostasis
