Simple Columnar Epithelial
Description: single layered, oval shapped nuclei at base of the cell, microvili, cillia
Function:
- movement of eggs - uteran tube
- absorption of nutrients from food - intestines (greater SA)
- protects lining, assists in absorption/secretion of bile - stomach, intestines, digestive glands, gallbladder
- reabsorption of water - kidney tubules
- lining - thyroid

Ciliated Columnar Epithelium
Description: single layer, oval nuclei at base of cell, cilia on surface, goblet cells - secretion of mucus
Function:
- move eggs - oviducts
- movement of mucus - upper respiratory tract, paranasal sinuses
- move cerebro-spinal fluid - central canal of spinal cord, brain ventricles

Stratified Squamous Epithelium
Description: many layers of cells, only top layer is sqamous, while underlying cells are cubodial/columnar (near basement membrane)
Basal cells are pushed upward to replace old squamous cells at the top.
