Epiglottis?
• The Epiglottis is a flap of cartilage that lies behind the tongue and in front of the entrance to the larynx.
• This flap allows air to flow through the larynx and into the rest of the respiratory system.
• It also allows the food to go down the esophagus, preventing the food from going down the air pipe.
• If both passages were open, food and drinks would get into the respiratory system and may cause Illness, Injury or Death!
• Here is an example!

The Esophagus
• The Esophagus is a hollow, muscular tube that carries food and liquids from the throat to the stomach for digestion. 10 to 14 inches in length of the esophagus
• If muscle weakens it can cause heart burn.
• Peristalsis is the operation in which the esophagus pushes the food down the tube for digestion.
