Homeostasis & The Digestive System

The Basic Definition of Homeostasis and the Digestive System

The definition of homeostasis: "The maintenance of a constant internal state in a changing environment." An example of how homeostasis works is body temperature. A normal body temperature is 98.6. Using homeostasis, the body can control temperature by making or releasing heat. Another example of homeostasis is the balance of pH.


The chemical and mechanical breakdown of food takes course in the digestive system. Food travels down the esophagus and then into the stomach, where gastric juices break down the chewed up food into smaller particles.


In the small intestine, the food is broken down so that proteins, vitamins, and minerals from the food can be absorbed into the body. The pancreas, liver, and gallbladder send different juices to the small intestine to help move along the process.


Next stop-the liver and the large intestine. Nutrient-rich blood flows into the liver where it filters out waste and other harmful substances. The liver figures out how many nutrients will be released to the body and how many will be kept in storage.The large intestine is where waste goes-and you can guess how that waste gets out.
