Physical and Chemical Changes Through the Digestive System Andrea Garcia Digestive System
The system that makes food absorbable into the body. Bolus
A small rounded mass of a substance of chewed food at the moment of swallowing. After he chewed the apple, it became BOLUS. The bolus traveled through and got to the esophagus Esophagus Esophagus
The esophagus is a soft muscular tube that moves food from pharynx to the stomach. After the Bolus traveled through the esophagus, it went to the stomach. Stomach
The digestive organ that is located in the upper abdomen, under the ribs. The upper part of the stomach connects to the esophagus, and the lower part leads into the small intestine. When food enters the stomach, it breaks down or mashes the food. After about 3 hours, the food becomes a liquid and moves into the small intestine, where digestion continues Small Intestines
The part of the intestine that runs between the stomach and the large intestine. The nutrients from digested food is absorbed into the bloodstream. Large Intestines
The large intestine is to absorb water from the remaining indigestible food matter and transmit the useless waste material from the body. Colon
The colon is a tube that connects the small intestine ti the rectum . Mouth
The mouth is were the digestive tract begins Liver
The liver is the body's largest internal organ. Your liver is the largest solid organ in your body. The liver does many jobs, but here are three big ones:
It cleans your blood. It produces an important digestive liquid called bile. It stores energy in the form of a sugar called glycogen. Gill bladder
It is responsible for digesting fats in food. People who have had there gallbladder removed will often have issues eating high fat meals because it is not as digested and causes very fast gastrointestinal distress(diarrhea). Pancreas
It plays an essential role in converting the food we eat into fuel for the body's cells. The pancreas has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar.
When getting in the pancreas is chemical change. Rectum
The rectum is a muscular ring that is at the end of the large intestine. Its function is to keep the intestine sealed shut until the need to pass feces arises. When that need arises it assists in the moving of the feces out of the body. Appendix
The researchers say it acts as a safe house for good bacteria, which can be used to effectively reboot the gut following a bout of dysentery or cholera Anus
The main function of the anus is to dispose of waste products out of the body. The anus is to eliminate the leftover waste solids in the body.
It is physical change because it releases the waste. The End'! Then the waste leaves the body through these process ! Both physical and chemical change. It is considered physical change because even though the food is bitten and broken down it is still food. It is also chemical change because the saliva beaks down the food as well When the food becomes bolus, it is physical change. This process is physical change because the food is just transferred to the stomach. This process is chemical because the bolus is partly digested In the small intestines is also a chemical change. Chemical change happens in the large intestines. It is a physical change. In the rectum chemical change happens. Chemical change happen in the appendix. This process is chemical change because the liver abrorbs materials and makes chemicals the body needs
