digestion
The process by which an organism breaks down its food into small units which can be absorbed.
vitamin
A chemical substance essential for the normal working of the human body
tongue
It moves the food around in the mouth to form the bolus.
pancreas
It makes several digestive juices which are squirted into the small intestine as chyme passes thru the pyloric sphincter. It also produces a base to neutralize the stomach acid.
stomach
It churns and mixes the food with gastric juices. The gastric juices contain stomach acid which destroys bacteria that might have been eaten and helps dissolve food. The gastric juices also contain digestive chemicals that start chemical digestion, turning the bolus into chyme.
small intestine
It chemically digests the food and allows the nutrients to be absorbed through its lining.
rectum
It pushes food out of the body through the anus.
salivary glands
They put saliva in the mouth. The saliva partially digests food and lubricates the mouth, making it easier for the tongue to form the bolus.
pharynx
It pushes food into the esophagus.
esophagus
It pushes food down into the stomach.
liver
Makes bile. Converts glucose to glycogen and back. Stores amino acids, fats. Retrieves them when needed.
gall bladder
It concentrates bile and squirts the bile into the chyme as the chyme enters the small intestine.
