Description of epithelium | closely packed cells,arrange single or multiple layers, always have apical surface, NO BV |
Function of epithelium | protection in areas high friction like esophagus, respiratory tract, anus absorption and found in kidney tuble, small intestine |
Simple means | one layer |
stratified means | multiple layers |
pseudostratified means | looks like more than one layer but isn't |
transitional means | shape changes depending on fullness of organ |
simple squamous epithelium is | one layer of thin "scale like cells" |
simple squamous epithelium is located | cardiovascular and lymphatic system ex.alveoli in lungs, Bc kidney,capillaries and other BV |
Simple squamous is part of.... | serous membranes |

simple cubodial epithlium function is | secretion and absorbtion ex are kidney tubles and glands |
simple cubodial epithlium location is | kidney tubles and surface of ovary |
simple columnar epithelium is | one layer of cylindrical cells with microvilli at apical surface and goblet cells |
simple columnar epithelium function is | secretion and abosorption( small intestine with microvillie) |
stratified squamous epithelium is | many layers that are flat deeper layers are cuboidal/columnar mitosis in deepest layers (BASAL Layers |
Stratified squamous epithelium location is | epidermis, sometimes contain keratin mouth, esphagus, anus and vagina not keratinized |
