HMB302H1 Study Guide - Final Guide: Simple Columnar Epithelium, Lymphadenopathy, Lymphatic Vessel
Document Summary
A group of similar cells performing a similar function (basic definition for tissue) Understand that the epithelial tissue is a classification only. Page 7: (the function is more enormous than this) The top layer of cells defines the classification for a stratified layer always look for the lumen.

Not viewing perpendicular to the bm - can"t be sure it"s simple squamous. Looking at it perpendicular if looking at the bm or the longitudinal section of a tube. *when looking through microscope, after finding the lumen, first look for division points, then classify the epithelium, then classify the connective tissue. The small layer of smooth muscle, the muscularis mucosa--vibration to spread food around for absorption.
