What we can use by taking advantage of human gastrointestinal cells?

Thegastrointestinal system processes food for energy and rids the body of solid waste. After food is chewed and swallowed, it enters the esophagus, a tube that carries food through the neck and chest to the stomach. When the gastrointestinal cells grow out of control, the gastrointestinal cancer starts such as gastrointestinal stromal tumors and carconoid tumors.
