Digestive System


The digestive system processes food, it breaks down protein, mineral, carbohydrates and fats along with other substances. The food gets broken down into soluble substances that the tissues absorb. There are two processes in digestion; mechanical and chemical processes.   The mechanical process is chewing, which makes the food into small particles, the mixing in the stomach, and the intestinal action.   The chemical process converts carbohydrates into simple sugars and breaks down protein into amino acids, these processes are done by specific enzymes.
The process starts with the mouth when a person starts to eat.   The food gets mixes with the salivary glands and produce secretions.   Starches are broken down by the saliva, then the food goes down the esophagus to the stomach, this happens in seconds. The stomach holds gastric juice; this juice has chemicals such as hydrochloric acid and enzymes such as pepsin lipase.   The pepsin is there to break down the proteins and the lipase breaks down the fat.   The stomach releases materials to the small intestine this occurs when the digestion is done.
When the solid food is digested the fluid remains, this is called chime. When the fluid is digested it passes through the pylorus sphincter and goes to the small intestine. In the small intestine the chyme absorbs the nutrients and flow to the bloodstream and leaves the remains.   The remains get passed to the colon, which is the large intestine and into the rectum.   The last process, the feces pass through the anal canal.   This is the process of the digestive system.
