This is an interactive educational powerpoint for grades 4th-5th on the human digestive system. The presentation allows students to review the major organs of the digestive system as well as the digestive process.
The mouth is where digestion first begins. Food starts in your mouth and you begin digestion by chewing with your teeth. Food mixes with your salvia to make a soft ball of food. Next the ball of food moves into the esophagus.

Food moves through your esophagus which is a tube that is about 25 cm long. It takes 4 to 10 seconds for your food to move through the esophagus. Your smooth muscles then move the food down toward the stomach.
The stomach is a muscular bag that can grow and shrink. Chemicals are mixed in with the food in your stomach in order to break it down. Food digests in your stomach for 2 to 4 hours until it becomes a liquid called “chyme”

Your small intestines is 4 to 7 meters in length. Most digestion takes place in the small intestines. Different chemicals are released into the small intestines to break down fats, carbohydrates, and proteins. The absorption of nutrients into your body also takes place in the small intestines.
The liver gives off a greenish fluid called bile which breaks up the fat in the food you eat. Fats are broken down in the small intestines. Your pancreas gives off chemicals that make a digestive solution which helps break down food in the small intestines. It also gives off insulin which lets sugar go into your blood stream
