Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
a. Epithelial tissues are classified by cell shape and the number of cell layers.
The epithelial tissue in the small intestine is specialized to absorb nutrients. Why would tight junctions be important in this function?
Tight junctions allow the cells to transmit ions between cells, allowing the cells of the epithelium to coordinate.
Tight junctions ensure all nutrients are absorbed through epithelial cells, allowing for selective permeabilty.
Tight junctions allow specific molecules such as nutrients to enter the cell more easily.
Tight junctions allow the epithelial cells to sense and recognize specific molecules.
