Mouth & Teeth
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.

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.
Quit
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” Quit

Small Intestines
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.
Quit
Liver & PancreasThe 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

Pancreas
Large Intestines
Your large intestine’s main job is to absorb water from the mass of food that has not been digested. This keeps water inside your body so that you do not dehydrate.
Quit
ColonYour colon is part of your large intestines.
The colon forms waste material that is going to be sent out of your body.
Quit
Rectum & Anus
The rectum and anus are part of your large intestines. They release your waste material from the body.
