The example you provided, columnar and epithelial cells, are found in various locations throughout the body but are most notable found in the intestinal lining of our intestines. The shape of the columnar which is made up of epithelial cells is waved shaped to allow for more surface area within a given location. Consequently, leading to further absorption.
