  1. The Digestive System By: Samantha It starts from chewing…

  2. How it starts • Lets say you eat a hamburger. Well you put it in your mouth and chew and chew in till it gets into tiny pieces. Then it goes down your esophagus and into your stomach. • Your digestivesystem started working even before you took the first bite of your hamburger. And the digestive system will be busy at work on your chewed-up lunch for the next few hours — or sometimes days, depending upon what you've eaten. This process, called digestion, allows your body to get the nutrients and energy it needs from the foods you eat.

  3. The Esophagus • The Esophagus is a tube that connects the pharynx and the stomach. • The esophagus is the tube that carries food, liquids and saliva from your mouth to the stomach.

  4. Peristalsis • Peristalsis is an automatic and important process that moves food through the digestive system. • Peristalsis are the movement that help squeeze the food down your esophagus.

  5. The Stomach • The Stomach’s inside wall is made up of millions of glands. • The food you have eaten is in the stomach for 4 hours breaking the nutrients up from the food to your body. • After the nutrients are broken up they are released into the small intestine.

  6. Glands • Glands is the wall in your stomach. • The glands make gastric juice which has special proteins and acids that break down the and digest the food.

  7. Small Intestine • The small intestine is made up of long narrow tunnels of muscle. • The small intestine is uneven and covered with fingerlike bumps. • These bumps are covered with even smaller bumps. Without these bumps the small intestine wouldn’t be able to absorb, or take in nutrients.

  8. Large Intestine • The large intestine is the part of the digestive system where waste products from the food you eat are collected and processed into faeces. • The nutrients that couldn’t be absorbed by the small intestine are passed into the large intestine.

  9. Your Body needs…. • Your body needs vitamins, minerals, carbohydrates, water, fats and protein. • Carbohydrates are found in rice and bread. • Fats are found in eggs and oil. • Proteins are found in meats and beans. • Vitamins help the body fight illnesses. • Minerals such as calcium help build up the bones

  10. What could go wrong? A lot of things can go wrong with the digestive system. Some people can’t digest their food as well as other people that’s how it becomes a problem. Many digestive problems are caused by not eating the right foods. You can get liver problems by drinking to much alcohol.
