Characteristics of Epithelial Tissues
Free Surface
Basement Membrane
Free Surface
Area of the tissue that doesn't touch another tissue
Basement Membrane
Basement order of protein/lipid glue that holds tissue in place to other tissues
Different Shapes of Epithelium
Squamous
Cuboidal
Columnar
Squamous
Thin, flat cells (squashed cells)
Cuboidal
Square like cells (cube cells)
Columnar
Tall, thin cells (column cells)
Different Layers of Epithelium
Simple
Stratified
Simple
One layer thick
Exchange of gases, liquids, and blood
Stratified
More than one layer thick
