Examines the functional properties of body structures and assesses the efficiency of their design
Explain the hierarchy of structural organization:
1. Chemical Level: atoms form molecules
2. Cellular Level: cells and organelles.
3. Tissue Level: a group of cells performing a common function.
4. Organ Level: a discrete structure made up of more than one tissue.
5. Organ System: organs working together for a common purpose.
6. Organismal level: the result of all simpler levels working in unison.
Describe 4 types of tissue:
1. epithelial: covers the surface and line cavities. (Ex: skin and GI tract)
2. connective: body support and protects organs. (Ex: fat, ligaments, bone, cartilage & blood)
