Concept #1: Four Functions of the Digestive System

Concept #2: Anatomy of the Digestive System

Concept #3: The Seven Sphincters

Practice: There is lots of smooth muscle in the walls of the GI tract. The contractions of this smooth muscle serve two functions: to break up food into smaller pieces and to move the food along the GI tract. Which of the following describe the role of smooth muscle in the walls of the GI tract? (Choose all that apply.)

Practice: A 21-year-old girl eats corn at a 4th of July barbecue. The corn is not digested and is removed from the body whole and unchanged in the feces. Through which of the following organs does the corn pass on its way from her mouth to the toilet? (Choose all that apply.)
