What is the function of the Digestive System?
What do each organs in the Digestive system do?
The Mouth is the beginning of the digestive system, the smell of food triggers the salivary glands in your mouth to secrete saliva, which causes your mouth to water.
The Esophagus which passes food from the pharynx to the stomach, which is about 25 cm in length, and the width varies from 1.5-2 cm.
The Stomach is the main food storage of the body. If the stomach didn't have the storage capacity, we would have to eat constantly instead of the normal 3-4 meals a day. The stomach also is the source where it secretes a mixture of acid, mucus, and digestive enzymes that help to digest and sanitize our food while it is being stored.
The Small Intestine is to absorb nutrients and minerals from food.
The Large Intestine absorbs and stores ions and nutrients released by gut bacteria and dissolved in water and used by the body for metabolism.
The Liver produces another digestive juice which is bile. The bile is stored between meals in the gallbladder.
The Pancreas produces a juice that contains a wide array of enzymes to break down the carbohydrate, fat, and protein in foods.
