The food girlfriend eat bring away an remarkable journey v your body, from height (your mouth) to bottom (your anus). Follow me the means the useful parts of her food space absorbed, offering you energy and also nutrients. This is a step-by-step account the the cradle system’s workings.
Structure that the cradle System

What is the digestive system?

Your digestive mechanism is comprised of the gastrointestinal (GI) tract and your liver, pancreas and gallbladder. The GI street is a series of hole organs that are associated to each other from your mouth to her anus. The guts that make up your GI tract, in the order the they are connected, include your mouth, esophagus, stomach, little intestine, large intestine and anus.

What walk the digestive device do?

Your digestive mechanism is uniquely created to do its project of turning your food right into the nutrients and also energy you should survive. And also when that done v that, it handily packages your solid waste, or stool, because that disposal when you have a bowel movement.

Why is digestion important?

Digestion is important because your body demands nutrients from the food you eat and the liquids friend drink in order come stay healthy and balanced and function properly. Nutrients incorporate carbohydrates, proteins, fats, vitamins, minerals and water. Her digestive system breaks down and absorbs nutrients from the food and also liquids friend consume to usage for necessary things choose energy, growth and also repairing cells.

What organs make up the digestive system?

The main organs that comprise the digestive system (in bespeak of their function) room the mouth, esophagus, stomach, little intestine, large intestine, rectum and anus. Help them along the way are the pancreas, bile bladder and also liver.

Here’s how these organs occupational together in your digestive system.



The mouth is the start of the digestive tract. In fact, cradle starts prior to you even take a bite. Your salivary glands get active as you see and smell that pasta dish or warm bread. After you start eating, girlfriend chew her food into pieces the are more easily digested. Your saliva mixes with the food to begin to rest it down right into a kind your body deserve to absorb and use. As soon as you swallow, your tongue passes the food into your throat and also into her esophagus.


Located in your throat near your trachea (windpipe), the stomach receives food from your mouth as soon as you swallow. The epiglottis is a tiny flap the folds over her windpipe together you swallow to prevent you indigenous choking (when food goes into your windpipe). A collection of muscular contractions in ~ the esophagus dubbed peristalsis it is provided food to her stomach.

But an initial a ring-like muscle in ~ the bottom of your esophagus dubbed the lower esophageal sphincter needs to relax come let the food in. The sphincter climate contracts and prevents the components of the stomach native flowing earlier into the esophagus. (When that doesn’t and also these materials flow ago into the esophagus, you might experience mountain reflux or heartburn.)


The stomach is a hollow organ, or "container," that holds food while that is being blended with stomach enzymes. This enzymes proceed the process of breaking down food into a usable form. Cell in the lining of your stomach secrete a strong acid and powerful enzymes that room responsible because that the malfunction process. As soon as the materials of the stomach space processed enough, castle released into the little intestine.

Small intestine

Made increase of three segments — the duodenum, jejunum, and also ileum — the little intestine is a 22-foot long muscular tube the breaks under food making use of enzymes released by the pancreas and also bile native the liver. Peristalsis additionally works in this organ, moving food through and also mixing it with digestive juices native the pancreas and also liver.

The duodenum is the first segment the the little intestine. It’s greatly responsible because that the consistent breaking-down process. The jejunum and ileum reduced in the intestine are largely responsible for the absorb of nutrients into the bloodstream.

Contents the the little intestine begin out semi-solid and also end in a liquid kind after passing with the organ. Water, bile, enzymes and also mucus contribute to the change in consistency. When the nutrients have actually been took in and the leftover-food residue liquid has actually passed with the little intestine, it climate moves on come the large intestine, or colon.


The kidnize secretes cradle enzymes into the duodenum that malfunction protein, fats and carbohydrates. The pancreas additionally makes insulin, pass it straight into the bloodstream. Insulin is the chief hormone in your body because that metabolizing sugar.


The liver has many functions, however its key job within the digestive system is to procedure the nutrients took in from the little intestine. Bile from the liver secreted right into the little intestine likewise plays an essential role in digesting fat and some vitamins.

The liver is her body's chemistry "factory." that takes the raw materials took in by the intestine and makes all the assorted chemicals her body demands to function.

The liver additionally detoxifies perhaps harmful chemicals. It division down and secretes countless drugs that have the right to be toxicity to your body.


The gallbladder stores and concentrates bile indigenous the liver, and then publication it right into the duodenum in the little intestine to help absorb and also digest fats.

Colon (Large Intestine)

The big intestine, or colon, is responsible for handling waste so the emptying the bowels is easy and also convenient. The a 6-foot lengthy muscular tube that connects the little intestine come the rectum.

The huge intestine is comprised of the cecum, the ascending (right) colon, the transverse (across) colon, the diminish (left) colon, and also the sigmoid colon, i beg your pardon connects to the rectum.

Stool, or waste left end from the digestive process, is passed v the colon by way of peristalsis, very first in a liquid state and also ultimately in a heavy form. As stool passes through the colon, water is removed. Stool is stored in the sigmoid (S-shaped) colon till a "mass movement" empties it right into the rectum once or double a day.

It generally takes about 36 hrs for stool to get through the colon. The stool chin is greatly food debris and bacteria. These “good” bacteria do several beneficial functions, such together synthesizing various vitamins, handling waste products and food particles and protecting versus harmful bacteria. When the to decrease colon becomes complete of stool, or feces, the empties its components into the rectum to start the process of removed (a bowel movement).


The rectum is a straight, 8-inch chamber the connects the colon come the anus. The rectum's task is to obtain stool native the colon, permit you understand that there is stool to it is in evacuated (pooped out) and also to organize the stool until evacuation happens. Once anything (gas or stool) comes into the rectum, sensors send a blog post to the brain. The brain then decides if the rectal contents can be released or not.

If castle can, the sphincters relax and the rectum contracts, disposing its contents. If the components cannot it is in disposed, the sphincter contracts and also the rectum accommodates so that the sensation temporarily walk away.


The anus is the last component of the digestive tract. That is a 2-inch lengthy canal consist of of the pelvic floor muscles and the 2 anal sphincters (internal and also external). The lining the the top anus is able to detect rectal contents. It allows you recognize whether the components are liquid, gas or solid.

The anus is surrounded by sphincter muscles that are important in permitting control of stool. The pelvic floor muscle creates an angle between the rectum and also the anus that stops stool from comes out once it’s not claimed to. The interior sphincter is constantly tight, other than when stool enters the rectum. This keeps us continent (prevents united state from pooping involuntarily) as soon as we are asleep or otherwise unaware that the existence of stool.

When we gain an advice to go to the bathroom, we count on our exterior sphincter to organize the stool until getting to a toilet, whereby it then relaxes to relax the contents.
