Teeth
• Chews up food into smaller pieces
• Mechanical Digestion
• Four types: Incisors, Canines, Pre-molars and Molars
Tongue
• Helps us swallow food after we chew it
Salivary Glands
Produces saliva
Saliva
Contains enzymes called amylase that break down starch in food
Oesophagus
• Long tube that connects from the mouth to the stomach
• Carries food from the mouth to the stomach
• Uses wave-like muscle contraction called peristalsis to push food down into stomach
Stomach
Further breaks down food with acids, bile and enzymes
Small intestine
Squeezes out all the nutrients from the food
Large Intestine
• Absorbs all the water from the food
• Starts forming faeces
Rectum
Stores faeces before excretion
Anus
Eliminates faeces as waste
Pancreas
Produces digestive enzymes and insulin
Liver
Creates bile
Gallbladder
Stores bile
Appendix
Function unknown
Ingestion
Food goes through the mouth, down the oesophagus and into the stomach
Digestion
Stomach produces enzymes to digest protein in the food and acids to break it up further
