Overview

Structure of the Digestive System

What is the digestive organisation?

Your digestive system is fabricated upwardly of the gastrointestinal (GI) tract and your liver, pancreas and gallbladder. The GI tract is a series of hollow organs that are connected to each other from your oral cavity to your anus. The organs that brand up your GI tract, in the order that they are connected, include your oral cavity, esophagus, stomach, pocket-sized intestine, large intestine and anus.

What does the digestive arrangement do?

Your digestive system is uniquely synthetic to do its job of turning your food into the nutrients and energy you demand to survive. And when it's done with that, it handily packages your solid waste matter, or stool, for disposal when you have a bowel motility.

Why is digestion important?

Digestion is important considering your body needs nutrients from the food y'all consume and the liquids y'all potable in gild to stay healthy and part properly. Nutrients include carbohydrates, proteins, fats, vitamins, minerals and water. Your digestive organization breaks downwardly and absorbs nutrients from the nutrient and liquids you swallow to employ for important things similar energy, growth and repairing cells.

What organs brand up the digestive system?

The main organs that make up the digestive organisation (in order of their function) are the mouth, esophagus, breadbasket, small-scale intestine, large intestine, rectum and anus. Helping them along the way are the pancreas, gall bladder and liver.

Hither's how these organs work together in your digestive organization.

Mouth

The mouth is the starting time of the digestive tract. In fact, digestion starts before you fifty-fifty accept a bite. Your salivary glands get agile as you lot see and olfactory property that pasta dish or warm staff of life. Later on you start eating, you chew your food into pieces that are more than easily digested. Your saliva mixes with the food to begin to break it downwards into a form your body can absorb and use. When you lot swallow, your tongue passes the food into your throat and into your esophagus.

Esophagus

Located in your throat near your trachea (windpipe), the esophagus receives nutrient from your oral fissure when y'all swallow. The epiglottis is a minor flap that folds over your windpipe as you consume to forbid you from choking (when nutrient goes into your windpipe). A series of muscular contractions within the esophagus called peristalsis delivers food to your stomach.

But first a ring-similar muscle at the bottom of your esophagus chosen the lower esophageal sphincter has to relax to let the food in. The sphincter then contracts and prevents the contents of the stomach from flowing dorsum into the esophagus. (When it doesn't and these contents menstruum back into the esophagus, you may feel acrid reflux or heartburn.)

Stomach

The stomach is a hollow organ, or "container," that holds food while information technology is existence mixed with stomach enzymes. These enzymes go on the process of breaking down nutrient into a usable class. Cells in the lining of your tummy secrete a strong acid and powerful enzymes that are responsible for the breakdown process. When the contents of the stomach are processed enough, they're released into the pocket-sized intestine.

Minor intestine

Fabricated upwards of 3 segments — the duodenum, jejunum, and ileum — the small intestine is a 22-foot long muscular tube that breaks down food using enzymes released by the pancreas and bile from the liver. Peristalsis too works in this organ, moving food through and mixing it with digestive juices from the pancreas and liver.

The duodenum is the starting time segment of the small intestine. It's largely responsible for the continuous breaking-down process. The jejunum and ileum lower in the intestine are mainly responsible for the absorption of nutrients into the bloodstream.

Contents of the small intestine start out semi-solid and end in a liquid course after passing through the organ. H2o, bile, enzymes and mucus contribute to the change in consistency. Once the nutrients have been absorbed and the leftover-nutrient residue liquid has passed through the pocket-size intestine, it and so moves on to the large intestine (colon).

Pancreas

The pancreas secretes digestive enzymes into the duodenum that interruption downwards protein, fats and carbohydrates. The pancreas too makes insulin, passing it directly into the bloodstream. Insulin is the chief hormone in your body for metabolizing carbohydrate.

Liver

The liver has many functions, just its chief job inside the digestive system is to procedure the nutrients absorbed from the modest intestine. Bile from the liver secreted into the pocket-sized intestine also plays an of import role in digesting fatty and some vitamins.

The liver is your body's chemic "manufacturing plant." It takes the raw materials absorbed by the intestine and makes all the various chemicals your body needs to function.

The liver also detoxifies potentially harmful chemicals. Information technology breaks downward and secretes many drugs that tin can be toxic to your body.

Gallbladder

The gallbladder stores and concentrates bile from the liver, and and then releases information technology into the duodenum in the modest intestine to help absorb and digest fats.

Colon

The colon is responsible for processing waste so that emptying your bowels is easy and convenient. Information technology'south a 6-foot long muscular tube that connects the pocket-sized intestine to the rectum.

The colon is fabricated up of the cecum, the ascending (right) colon, the transverse (across) colon, the descending (left) colon, and the sigmoid colon, which connects to the rectum.

Stool, or waste left over from the digestive process, is passed through the colon by ways of peristalsis, first in a liquid state and ultimately in a solid class. As stool passes through the colon, water is removed. Stool is stored in the sigmoid (S-shaped) colon until a "mass motion" empties information technology into the rectum once or twice a day.

It ordinarily takes about 36 hours for stool to become through the colon. The stool itself is mostly food debris and bacteria. These "good" leaner perform several useful functions, such as synthesizing various vitamins, processing waste material products and food particles and protecting against harmful leaner. When the descending colon becomes full of stool, or feces, it empties its contents into the rectum to begin the process of elimination (a bowel movement).

Rectum

The rectum is a straight, 8-inch chamber that connects the colon to the anus. The rectum's task is to receive stool from the colon, let you know that there is stool to be evacuated (pooped out) and to hold the stool until evacuation happens. When anything (gas or stool) comes into the rectum, sensors send a message to the encephalon. The brain so decides if the rectal contents tin can be released or not.

If they tin can, the sphincters relax and the rectum contracts, disposing its contents. If the contents cannot exist disposed, the sphincter contracts and the rectum accommodates so that the sensation temporarily goes away.

Anus

The anus is the last office of the digestive tract. It is a 2-inch long canal consisting of the pelvic floor muscles and the two anal sphincters (internal and external). The lining of the upper anus is able to detect rectal contents. It lets you know whether the contents are liquid, gas or solid.

The anus is surrounded by sphincter muscles that are important in allowing command of stool. The pelvic flooring musculus creates an angle betwixt the rectum and the anus that stops stool from coming out when it'southward non supposed to. The internal sphincter is always tight, except when stool enters the rectum. This keeps us continent (prevents us from pooping involuntarily) when we are asleep or otherwise unaware of the presence of stool.

When we get an urge to get to the bathroom, nosotros rely on our external sphincter to hold the stool until reaching a toilet, where it then relaxes to release the contents.
