The epithelial tissue in the small intestine is specialized to absorb nutrients. Why would tight junctions be important in this function?

• A. Tight junctions allow the cells to transmit ions between cells, allowing the cells of the epithelium to coordinate. 
• B. Tight junctions ensure all nutrients are absorbed through epithelial cells, allowing for selective permeabilty. 
• C. Tight junctions allow specific molecules such as nutrients to enter the cell more easily. 
• D. Tight junctions allow the epithelial cells to sense and recognize specific molecules.
