Digestive System

Mouth

• This is where we ingest food (eat our food)
• We do this using our teeth: Canine, Incisors, Molar

• Canine teeth stab and rip food

• Incisors cut our food

• Our molar masticate (grind) the food

• The Salivary Glands release saliva into our mouth

• Saliva starts to break down sugars and lubricates the food

• This is a tube connecting the mouth to the stomach

• Food is pushed down to the stomach by the action of peristalsis

Stomach

• The stomach mixes food into a paste. 

• Some food is torn down in the stomach. 

• Stomach acid removes bacteria.

Duodenum

• This is the first part of the Small Intestine

• More chemicals are joined in from the Pancreas and Gall Bladder

Pancreas

• This adds a chemical into the duodenum to neutralize the stomach acid

• The Pancreas also adds more chemicals into the duodenum to break down food. 

Why do we have a mouth?
