Microvilli on the surface of epithelial cells such as those lining the intestine increase the cell's surface area and thus facilitate the absorption of ingested food and water molecules.
Gland of Colon/Colon Mucosa – Transversely cut glands are seen to consist of simple columnar epithelium surrounded by a tubular lumen and embedded in lamina propria with many free lymphocytes. Lymphocytes can also be seen penetrating the epithelium.
Enamel is the thin outer covering of the tooth. This tough shell is the hardest tissue in the human body. Enamel covers the crown which is the part of the tooth that's visible outside of the gums. Because enamel is translucent, you can see light through it.
