Your digestion system consists of the digestion tract — also called the gastrointestinal (GI) tract — and the liver, gallbladder and pancreas. The digestion tract is basically a series of hollow organs jointed in a twisting tube from the mouth all the method to the rectum. The mouth, stomach, esophagus, small and large intestinal tracts, rectum and rectum are the hollow organs the GI tract is comprised of. The solid organs of the gastrointestinal system are the liver, gallbladder and pancreas. Your gastrointestinal system activates whenever you eat something and assists the body absorb food and absorb nutrients from it. However do you understand the order of digestive system and their functions?
Order of Human Digestive System
You may learn about a few of the solid and hollow organs included in the digestion system, but not many have complete details about them. Now let’s get a closer to digestive system in order:
1) The Mouth
When you start chewing something, your salivary glands begin producing saliva to oil your food. Your break down your food and your tongue mixes it up with saliva. There are three pairs of salivary glands in your mouth — the sublingual, parotid and submandibular glands. These glands produce up to a liter of saliva every day.

2) The Esophagus
Your tongue, teeth and saliva will turn your food into a soft, round mass that will make it simple to swallow. There are muscles in your throat and mouth used to push food to your esophagus, which is the tube linking your stomach with your throat. The esophagus likewise has muscles that produce integrated waves to move your food into your stomach. It operates in a methodical way — the muscles behind the round mass of food you have in the esophagus will contract to press it forward and the muscles ahead of it will unwind to make it simple for your food to take a trip to your stomach. When your food reaches the lower end of the esophagus, a muscular valve, called the lower esophageal sphincter, feels the pressure from the food and opens up to let what you eat enter your stomach.

3) The Stomach
You have powerful muscles in your stomach that aid to break down your food into smaller sized pieces. The gastrointestinal glands in your stomach will likewise produce enzymes and stomach acid. The combination of stomach acid and enzymes turn the food into a paste called chyme. Your abdominal muscle will then contract to push the chyme to your small intestine. The food will get in the small intestine through a valve called the pylorus. The pylorus releases a small amount of food at a time.

4) Small Intestine
Small intestine comes next in the order of gastrointestinal system. The digestion will continue even when your food has entered your duodenum, the first area of your small intestine. A variety of digestion juices released by liver, pancreas and gallbladder will enter your small intestine for complete digestion of food. Pancreas produces enzymes to break down carbohydrates, proteins and fats, whereas the liver produces bile to absorb fats. The wall of your small intestine likewise produces other juices for food digestion. The food will then move into the second area of your small intestine where it will turn into smaller sized particles of nutrients. After that, it moves into the last portion of your small intestine where the remaining nutrients are soaked up.
The pancreas secretes digestive enzymes into the duodenum, the first sector of the small intestine. These enzymes break down protein, fats, and carbs. The pancreas also makes insulin, producing it straight into the bloodstream. Insulin is the chief hormone for metabolizing sugar.
The liver has several functions, however its main function within the gastrointestinal system is to process the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an essential function in digesting fat. In addition, the liver is the body’s chemical “factory.” It takes the raw products soaked up by the intestinal tract and makes all the various chemicals the body needs to function. The liver also cleanses potentially hazardous chemicals. It breaks down and produces lots of drugs.
The gallbladder stores and concentrates bile, and then releases it into the duodenum to help soak up and digest fats.
8) Colon (large intestinal tract)
The colon is a 6-foot long muscular tube that connects the small intestine to the anus. The large intestinal tract is made up of the cecum, the rising (right) colon, the transverse (across) colon, the coming down (left) colon, and the sigmoid colon, which connects to the anus. The appendix is a small tube connected to the cecum. The big intestinal tract is an extremely specialized organ that is responsible for processing waste so that clearing the bowels is easy and hassle-free.
Stool, or waste left over from the digestion procedure, is gone through the colon by methods of peristalsis, first in a liquid state and ultimately in a solid type. As stool travels through the colon, water is gotten rid of. Stool is stored in the sigmoid (S-shaped) colon until a “mass motion” clears it into the anus once or twice a day. It typically takes about 36 hours for stool to get through the colon. The stool itself is primarily food debris and bacteria. These bacteria perform a number of helpful functions, such as synthesizing various vitamins, processing waste products and food particles, and protecting against damaging bacteria. When the descending colon becomes loaded with stool, or feces, it empties its contents into the anus to start the procedure of elimination.
The anus (Latin for “straight”) is an 8-inch chamber that links the colon to the anus. It is the anus’s job to receive stool from the colon, to let the individual understand that there is stool to be evacuated, and to hold the stool up until evacuation happens. When anything (gas or stool) enters the anus, sensing units send a message to the brain. The brain then decides if the rectal contents can be released or not. If they can, the sphincters unwind and the anus contracts, disposing its contents. If the contents can not be disposed, the sphincter agreements and the anus accommodates so that the feeling momentarily disappears.
