Anatomy vs physioglogy
Sketal system - names of bones, actions - cellular function and shaping throughout life
Chemical Level
Atoms (e.g., C, H, O)
Molecules (e.g., DNA, glucose)
Cellular level
Basic structural/functional units
Tissue level
Groups of cells that perform a
particular function
4 types – epithelial, connective,
muscular, nervous
4 types of tissue –
epithelial, connective, muscular, nervous
epithelial tissue
forms inner and outer of linnings organs
connective tissue
bone tissue, cartliage, blood, fat
muscular Tissue
contract
nervous tissue
transmit electrical signals
Organ level
Composed of two or more types of tissues that have specific functions
e.g., stomach, heart, brain
System level
Composed of related organs with a common function
e.g., digestive system
(mouth, esophagus, stomach, etc.)
