Organs
Combination of tissues that form into anatomical units that have multiple functions.
Gross Anatomy or Macroscopic Anatomy
Considers relatively large structures and features visible to the unaided to the unaided eye.
Levels of Organization
From low to high:
- Chemical or molecular levels
- Cellular level
- Tissue level
- Organ level
Homeostasis
Characteristics of the internal environment will be relatively stable at all levels.
Differentiation
Individual cells become specialized to perform particular functions.
