Answer 4

Simple Columnal Epithelium
Function: Epithelium allows for absorbtion of nutrients
Location: Intestines
Features: Contains villi, which are finger projections that help to break down complex nutrients to help absorbtion and goblet cells, that produce mucous to prevent debris from attaching to the outside
