How these organs help our bodies digest food and how they are important :

Oesophagus - The esophagus is the food chube that takes the food from the throat to the stomach and its series of contractions using small muscles called peristalsis.

Stomach - When food gets to the stomach, the stomach acids and enzymes, which are made there, to help mix the food by the action of muscles in the stomach wall. The pyloric sphincter is a muscular valve that opens to allow the food to pass from the stomach to the small intestine.

If it were not for the stomach's storage capacity, we would have to eat constantly instead of just a few times each day. The stomach also secrets a mixture of acid, mucus, and digestive enzymes that helps to digest our food while it's been stored.


Small intestine - The small intestine carries out most of the digestive tasks, absorbing almost all of the nutrients you get from into your bloodstream. The walls of the small intestine make digestive juices, or enzymes, that work together with enzymes from the liver and pancreas to do this.

Small intestines are important because the main job for them is to break down, digest the food, and to absorb nutrients.


Large intestine - The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place. The waste is then collected as feces and it waits to be excreted.


Liver - The liver's main job is to filter the blood coming from the digestive tract, before passing it to the rest of the body. The liver also detoxifies chemicals and drugs. As it does so, the liver secretes bile that ends up back in the intestines.

Our liver stores important vitamins and nutrients from the food we eat and stocks them up for when we need them later, the harmful things we take in like alcohol, and drugs, but without the liver, the body cannot process these items.


Rectum - The rectum is an eight inch chamber that connects the colon to the anus. The rectum’s job 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.

The rectum is important, because it stores all the waste before it comes out.


Anus - The anus is the last part 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.
