The Journey Of DInner In The Human Body
This storyboard does not have a description.
When food is chewed up in the mouth, it is mixed up with the enzyme Amylase which breaks down Starch into Glucose. The tongue helps to mix the food and enzyme together.
When the food is swallowed it goes into the esophagus. The esophagus has two sets of muscle fibers, the longitudinal muscles (which go down the esophagus) and the circular muscles (which go round the esophagus). The esophagus takes food into the stomach.
Inside the stomach the food is met by Hydro-Clorich Acid and the enzyme Protease which breaks down Protien into Amino Acids. Hydro-Clorich Acid also contains Rennin which turns milk into a solid. The Hydro-Clorich Acid kills most bacteria and makes the enzyme work.
There are 2 parts of the small intestine the duodenum and the ileum. Bile and pancreatic juice are added to the food in the duodenum. Intestinal juice is mixed with the food as it passes along the ileum. In the small intestine, the food meets the enzyme Lipase which breaks down Dietary Fats. Also, the walls of the small intestine start absorbing what is needed into the body.
Next, the food travels to the liver where liquids are absorbed into the bloodstream.
