The Digestive System

The Digestive System

• By Samantha
• It starts from chewing

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 digestive system 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.

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.

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 Stomachs 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.

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 wouldnt
  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 couldnt be absorbed by the
  small intestine are passed into the large
  intestine.

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
