Protected regions where absorption takes place
Ex: Kidneys, Lungs, Heart
Simple Squamous Epithelium

Limited protection where absorption/secretion happens
Ex: Pancreas, Salivary Glands
Simple Cuboidal Epithelium

Some protection, absorb, secrete Ex: Stomach, Intestines
Simple Columnar Epithelium

All cells touch basement membrane Nuclei at different places Looks layered Have cilia Ex: Nasal cavity, Trachea, Bronchi
Pseudostratified Epithelium
