Ever wonder how the digestive system works? It all starts when you first chew your food with your teeth, which is a chemical digestion. Enzymes will be pushed down by the tongue.
The food goes down through the esophagus.
After swallowing your food, the and enzymes will head back towards your esophagus, which connects the throat to the stomach.
The enzymes are now located in your stomach! They will be mixed with other enzymes which will be broken down by digestive juices.
A lining of mucus protects your stomach from the digestive juices. After four hours, food is like a thick milkshake, which is known as chyme.
First, however, we should mention the duodenum which is filled with digestive juices from the liver and pancreas. They turn the chyme into a soup of molecules.
A Villi is a any of numerous minute elongated projections set closely together on a surface, hair found in the small intestine. Cells on the surface of the villi absorb nutrients from the chyme.
The chyme later moves into the small intestine, where most of the nutrients are absorbed.
This is an example of a villi.
Now, we talk about the large intestine! The large intestines job is to suck out the water from the digested chyme. This process is known as absorption.
This step is important because recovering this water keeps you from getting dehydrated.
Once most of the water is absorbed, the solid waste will move towards the rectum, which is the last part of the large intestine. When enough waste piles up, it is all sent to the outside world. The digestive process is now complete!
