The path food takes through the digestive system and how it is actually digested involves many parts and organs involved in the digestive system. The organs or components involved include the many parts of the mouth and throat before it enters the stomach. The digestive process begins with the salivary glands that are initiated at the sight and smell of food. Food then takes its journey through the mouth, at which time the food is chewed and transformed into a substance called bolus for digestion. Saliva moistens the food to cause this transformation. To make able to swallow, the food, or bolus now, enters the pharynx to the esophagus. The pharynx is connected to the stomach where stomach acids transform the bolus into chime, the semi liquid substance that enables the stomach to partially digest the food. Depending on the size and type of food eaten, this process can usually take between 2 to 6 hours. Once the chyme reaches the small intestine, the liver, gallbladder and pancreas contribute to the digestive

It is broken down into three more parts such as the duodenum, the jejunum and the ileum. The liver and gallbladder secrete bile helping with the digestion and absorption of fat. Enzymes and bicarbonate secretions of the pancreas further aid the entire process. The leftovers which are not absorbed then enter the large intestine through the sphincter, keeping it from reentering the small intestine. Organs included in the large intestine are the colon and rectum, in which the additional absorption of water and vitamins occurs. The materials that are not absorbed are then eliminated by excretion from the anus. These waste products complete the digestive process after leaving the body through the external opening of the digestive tract....
