The food friend eat bring away an remarkable journey v your body, from height (your mouth) come bottom (your anus). Follow me the means the advantageous parts of your food are absorbed, offering you energy and also nutrients. Here’s a step-by-step account the the cradle system’s workings.
Structure of the cradle System

What is the cradle system?

Your digestive mechanism is made up of the gastrointestinal (GI) tract and also your liver, pancreas and also gallbladder. The GI street is a series of hollow organs the are linked to each other from your mouth to your anus. The guts that consist of your GI tract, in the order the they room connected, incorporate your mouth, esophagus, stomach, little intestine, big intestine and also anus.

What go the digestive mechanism do?

Your digestive device is uniquely built to carry out its project of turning your food right into the nutrients and also energy you need to survive. And also when it’s done with that, it handily packages your solid waste, or stool, because that disposal when you have actually a bowel movement.

Why is cradle important?

Digestion is important since your body demands nutrients from the food you eat and also the liquids girlfriend drink in order to stay healthy and duty properly. Nutrients incorporate carbohydrates, proteins, fats, vitamins, minerals and water. Your digestive mechanism breaks down and also absorbs nutrients from the food and also liquids girlfriend consume to use for crucial things like energy, growth and also repairing cells.

What organs comprise the cradle system?

The main organs that consist of the digestive system (in bespeak of their function) room the mouth, esophagus, stomach, tiny intestine, big intestine, rectum and anus. Helping them along the method are the pancreas, bile bladder and liver.

Here’s exactly how these organs work-related together in her digestive system.



The mouth is the start of the digestive tract. In fact, digestion starts prior to you also take a bite. Her salivary glands get active as girlfriend see and smell the pasta food or warmth bread. After ~ you start eating, girlfriend chew her food right into pieces the are much more easily digested. Her saliva mixes through the food to begin to break it down into a kind your body can absorb and use. When you swallow, her tongue passes the food right into your throat and into your esophagus.


Located in your throat close to your trachea (windpipe), the esophagus receives food from your mouth as soon as you swallow. The epiglottis is a tiny flap that folds over your windpipe together you gulp down to avoid you indigenous choking (when food goes right into your windpipe). A collection of muscular contractions within the esophagus referred to as peristalsis delivers food to your stomach.

But first a ring-like muscle in ~ the bottom of your esophagus called the reduced esophageal sphincter needs to relax to let the food in. The sphincter then contracts and prevents the materials of the stomach indigenous flowing back into the esophagus. (When that doesn’t and these materials flow earlier into the esophagus, you may experience mountain reflux or heartburn.)


The stomach is a hollow organ, or "container," that holds food while the is being mixed with stomach enzymes. These enzymes continue the procedure of breaking under food right into a usable form. Cell in the lining of your stomach secrete a solid acid and an effective enzymes that room responsible because that the malfunction process. When the contents of the stomach are processed enough, they’re released into the little intestine.

Small intestine

Made up of 3 segments — the duodenum, jejunum, and also ileum — the little intestine is a 22-foot lengthy muscular tube the breaks down food using enzymes exit by the pancreas and also bile native the liver. Peristalsis also works in this organ, relocating food through and also mixing it with digestive juices indigenous the pancreas and also liver.

The duodenum is the first segment the the tiny intestine. It’s mostly responsible for the consistent breaking-down process. The jejunum and ileum reduced in the intestine are mainly responsible for the absorb of nutrients into the bloodstream.

Contents the the small intestine begin out semi-solid and end in a liquid form after passing through the organ. Water, bile, enzymes and also mucus add to the readjust in consistency. As soon as the nutrients have been soaked up and the leftover-food residue liquid has actually passed with the tiny intestine, it climate moves on to the big intestine, or colon.


The pancreas secretes digestive enzymes into the duodenum that break down protein, fats and also carbohydrates. The pancreas likewise makes insulin, passing it directly into the bloodstream. Insulin is the cook hormone in your body for metabolizing sugar.


The liver has countless functions, but its key job within the digestive device is to process the nutrients soaked up from the small intestine. Bile native the liver secreted into the tiny intestine also plays critical role in digesting fat and also some vitamins.

The liver is her body's chemistry "factory." the takes the life materials took in by the intestine and also makes every the miscellaneous chemicals your body demands to function.

The liver additionally detoxifies potentially harmful chemicals. It breaks down and secretes countless drugs that have the right to be toxic to your body.


The gallbladder stores and also concentrates bile indigenous the liver, and then releases it right into the duodenum in the small intestine to aid absorb and 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 long muscular tube the connects the little intestine come the rectum.

The large intestine is comprised of the cecum, the ascending (right) colon, the transverse (across) colon, the descending (left) colon, and the sigmoid colon, i m sorry connects come the rectum.

Stool, or garbage left end from the cradle process, is passed v the colon by way of peristalsis, an initial in a liquid state and ultimately in a solid form. Together stool passes v the colon, water is removed. Stool is save in the sigmoid (S-shaped) colon until a "mass movement" empties it into the rectum as soon as or twice a day.

It normally takes around 36 hrs for stool to gain through the colon. The stool chin is largely food debris and bacteria. This “good” bacteria do several helpful functions, such together synthesizing miscellaneous vitamins, processing waste products and also food particles and protecting against harmful bacteria. Once the to decrease colon becomes complete of stool, or feces, it empties its materials into the rectum to begin the process of remove (a bowel movement).


The rectum is a straight, 8-inch chamber that connects the colon come the anus. The rectum's task is to get stool from the colon, allow you understand that there is stool to be evacuated (pooped out) and also to hold the stool till evacuation happens. As soon as anything (gas or stool) comes right into the rectum, sensors send a post to the brain. The brain then decides if the rectal components can be exit or not.

If they can, the sphincters relax and also the rectum contracts, getting rid of its contents. If the components cannot it is in disposed, the sphincter contracts and also the rectum accommodates so the the emotion temporarily goes away.


The anus is the last component of the cradle tract. The is a 2-inch lengthy canal consists of the pelvic floor muscles and also the two anal sphincters (internal and also external). The lining of the upper anus is able come detect rectal contents. It lets you understand whether the contents are liquid, gas or solid.

The anus is surrounded by sphincter muscles the are necessary in allowing control the stool. The pelvic floor muscle create an angle in between the rectum and the anus the stops stool from comes out once it’s not an alleged to. The internal sphincter is always tight, except when stool enters the rectum. This keeps united state continent (prevents united state from pooping involuntarily) when we space asleep or otherwise unaware the the presence of stool.

When we obtain an advice to walk to the bathroom, we depend on our exterior sphincter to host the stool until reaching a toilet, wherein it then relaxes to release the contents.
