List the organs of the digestive tract and state the contribution of each in the digestive process
Answers
Answer:
Explanation:Digestion is the complex process of turning the food you eat into nutrients, which the body uses for energy, growth and cell repair needed to survive. The digestion process also involves creating waste to be eliminated.
The digestive tract (or gastrointestinal tract) is a long twisting tube that starts at the mouth and ends at the anus. It is made up of a series of muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food. Along the way are three other organs that are needed for digestion: the liver, gallbladder, and the pancreas.

Food's Journey Through the Digestive System
Stop 1: The Mouth
Checkups and Tests You Shouldn't Miss
When's the last time you had your cholesterol, blood pressure, or weight checked? Learn which medical tests and screenings you should have and how often you should have them.
The mouth is the beginning of the digestive system, and, in fact, digestion starts here before you even take the first bite of a meal. The smell of food triggers the salivary glands in your mouth to secrete saliva, causing your mouth to water. When you actually taste the food, saliva increases.
Once you start chewing and breaking the food down into pieces small enough to be digested, other mechanisms come into play. More saliva is produced. It contains substances including enzymes that begin the process of breaking down food into a form your body can absorb and use. Chew your food more -- it also helps with your digestion.
Stop 2: The Pharynx and Esophagus
Also called the throat, the pharynx is the portion of the digestive tract that receives the food from your mouth. Branching off the pharynx is the esophagus, which carries food to the stomach, and the trachea or windpipe, which carries air to the lungs.
The act of swallowing takes place in the pharynx partly as a reflex and partly under voluntary control. The tongue and soft palate -- the soft part of the roof of the mouth -- push food into the pharynx, which closes off the trachea. The food then enters the esophagus.
