The digestive system maintains homeostasis by creating the proper pH balance in the gastric environment. In addition, by maintaining the correct enzyme ratio, the digestive system nurtures beneficial bacteria that inhibit disease and produce biological substances the body needs such as vitamin K.Know More
Homeostasis is the balance the body maintains to continue to function properly. All the bodily systems, including the digestive system, contribute to homeostasis. The body maintains homeostasis using both positive and negative mechanisms. Negative feedback occurs when the body senses an imbalance, and the various systems work to counterbalance and restore proper equilibrium. Positive feedback happens when the body senses a change and works to enhance it.
The body's pH balance, its ratio of acid and alkaline, is an important part of overall homeostasis. In the mouth, saliva is only slightly acidic. However, the digestive system needs and maintains a highly acidic environment in which to rapidly break down food. Along with the regulation of the pH balance, the digestive system maintains microflora such as acidophilus and bifidobacterium that break down cancer-causing carcinogens and other infections. After it breaks down food through a complex conveyer-like system, the digestive system passes needed nutrients on to the circulatory system for absorption by the body.Learn more about Organs
The digestive system involves the mouth, throat, esophagus, stomach, small intestine, large intestine, pancreas, liver and gallbladder. The main organs involved in digestion include the esophagus, stomach, and the small and large intestines.Full Answer >
The esophagus is a long, muscular tube that connects an animal’s stomach to its mouth. Distinct from the windpipe, which transports air into and out of the lungs, the esophagus usually carries food and water from the mouth to the stomach. However, during vomiting, the esophagus carries stomach acids and undigested food from the stomach back out through the mouth. The esophagus is about 1 inch in diameter, and approximately 10 to 14 inches in length.Full Answer >
The stomach is the primary organ that breaks down food as it enters the digestive system. This organ receives food from the esophagus and eventually directs the partially digested food into the small intestine. It also helps kill harmful bacteria.Full Answer >
The liver is an essential part of the human digestive system. It is an accessory organ of the digestive system that assists with digestive processes without being directly involved with food digestion. The liver assists the digestive system by secreting bile and bile salts to help emulsify fats and aid in their digestion in the small intestine.Full Answer >
