  replaced with permanent teeth.

The Skeleton

• The skeleton is all the bones in your body.
• You have about 206 bones in your body.
• Bones protect organs such as the brain, the
  heart, and our lungs.
• Bones give us shape. Without our skeleton, we
  would be a blob of tissue on the floor.
• Bones help us to move. Muscles are attached to
  our bones, when our muscles move, they move the
  bones, and we move.

Muscles

• Bones and muscles work together.
• Muscles are body parts under the skin that helps
  the bones move.

  and legs.

The Heart

• Your heart is a muscle that pumps blood to every
  part of your body.
• It is about the size of your fist and weighs less
  than a pound.
• It keeps you alive.
• Your heart pumps more than 5 quarts of blood
  through the body every minute.
• Your heart rate is how fast or slow your heart
  beats. Your heart beats about 72 times a minute.

What do you think will happen to our heart rate
when we exercise?

Lungs

• Your lungs are body parts that help you breathe
  the air you need to live.
• You have two lungs.
• When you breathe air through your mouth or nose,
  the air goes down a tube to your lungs.
• When you breathe your chest expands.

16
How does your heart and lungs work together?

• Your heart and lungs help keep you alive.
• Your heart and lungs carry oxygen to all parts of
  the body.
• Exercise makes the heart and lungs stronger and
  healthier.

Lets learn how our body digests food.
Digest means to break down food in the body.
18
Esophagus

• When you chew your food, it mixes with a liquid
  in your mouth called saliva.
• Saliva helps break down food.
• Once food has been chewed and swallowed, it goes
  down a tube called the esophagus.

19
Stomach

• Once the food goes down the esophagus, the food
  enters the stomach.
• The stomach continues to break down the food. It
  has muscles that mash food into a sloppy soup.

20
Large and Small Intestines

• Food leaves the stomach and enters the small
  intestine. Nutrients your body needs from the
  food you eat goes to all parts of the body.
• You have about 20 feet of small intestines.
• Food that your body does not need goes to the
  large intestine.

Digestive System

• Digestion begins when food enters the mouth where
  saliva and teeth break it down.
• Once food has been chewed and swallowed, it goes
  down a tube called the esophagus to the stomach.
• Stomach muscles mix the food and moves it to the
  small intestine.
• Food that your body does not need goes to the
  large intestine.
