My hand is an example of epithelial tissue because it is covered
with it. Epithelial tissue, also known as epithelium is sheets of body tissue
that covers and lines the external and internal surface of the entire body. It
is made up of tightly and densely packed cells. Epithelial tissue is
categorized according to how many cell layers it has and the shape of the
cells. The epithelial tissue helps my hands protect, sensate, excrete, diffuse,
and absorb. Epithelial tissue is considered as avascular because it lacks blood
vessels.
