Ingest & chew food Mechanical Digestion- chewing Chemical Digestion- amylase- a special chemical called an enzyme that breaks starches into sugars
Transports food from mouth to stomach by way of peristalsis.
Breaks down food and soaks it in acid (gastric juice) to begin digestion of Proteins. Coated in a thick mucus to protect itself from its own acids. When there is a hole in this mucus, the acid burns a hole in the stomach called an ulcer.
*Accessory Organ-food does not travel here, but it participates from the side lines. Digests nutrients Sends chemicals to appropriate places in the body Filters waste out of the blood! Stores vitamins and minerals
*Accessory Organ Collects waste from the liver Makes bile – which helps digest fats!
*Accessory organ Produces juices that aid in digestion Delivers these juices to the small intestine
Received food from the stomach Extracts chemicals and nutrients through blood vessels in the villi (finger-shaped structures attached to the intestine wall)
Soaks up water and solidifies waste (makes poop) Removes waste from the body Cleans intestine by moving indigestible food (fiber) through them to remove waste. If too much water taken out = constipation If too LITTLE water taken out = diarrhea
