Description:

- be able to identify simple columnar epithelium by understanding its morphology

- know where simple columnar epithelium is located

- know that this tissue has microvilli on its apical surface to increase its absorption ability

- know what a goblet cell is and what it produces and secretes

- have microvilli on the apical (top) surface of the cells
- also contain many mucous producing cells called goblet cells
- found in areas of the body with high levels of mucus secretion and where absorption takes place such as the kidneys and lining of the small intestine

Images of Simple Columnar Epithelium

Here are some images of simple columnar epithelium for you to study. On the last image you can see the vasculature of the intestinal villi. I put this in here to illustrate the importance of absorbing food into the bloodstream and how this is done.
