Transcript of Digestive System

The Digestive System By: Ester Velazquez Large Intestine(Colon) -This is where the rest of your food comes out through. -It produces mucous. Stomach -The second part of the system. -It breaks down the food that has not been broken down yet. -The stomach has strong muscular walls. Mouth -The frst part of the system. -The smell of food calls the salivary glands. -The food has to be broken down before swalling. -The food breaks down by your saliva and your teeth. -AS your mouth breaks down the food more saliva and juice are produced. -It collects water. -It gets vitamins. -When all of those things get together they produce what we call POO.
