These organs all break down food into tiny little pieces, so it can be digested afterwards.

2) Pancreas, Gallbladder, Liver

One cannot think well, love well, sleep well, if one has not dined well.

This is the tissue that supports and position all the digestive organs in the right place.

4) Mesentary

These four cell types work together to digest the broken down food and then transport the final products to where it’s needed.

3) Enzymes, Hormones, Nerves, Blood

Made up of ten organs and over 20 different specialised cell types, the digestive system transforms food into nutrients and energy for the body, that keep you alive and healthy. It consists of four different parts:

Digestive System

<ol><li>Leftover fiber water and dead cells from the digestion make their way through the large intestine. Most of the water is drained out, leaving stool</li><li>This then is squeezed into the rectum and expells the waste through the anus</li></ol>The entire process usually takes in between 30 and 40 hours.

The Disposal

It’s a long tube that transports all your food through one end of your body to the other. During this trip down your body it is broken apart, digested and then the rest is disposed.

1) Gastrointestinal Tract

<ol><li>Saliva is produced before eating</li><li>You crush the food in your mouth and mix it with the saliva, this mix is called the bolus. Enzymes in the saliva break down any starch</li><li>The bolus then travels down your esophagus into your stomach</li><li>The muscles in the stomachs wall pound the bolus into little bits. Hormones then trigger acids and enzymes that help break down the food</li><li>The liver, gallbladder and pancreas create digestive juices and bile which are then transported to the small intestine where fat is disolved and protein and carbs are broken down. These are transported through blood to the final organs</li></ol>

Across the planet, humans eat on average between 1 and 2.7 kilograms of food a day, and every last scrap makes its way through the digestive system. Comprised of ten organs covering nine meters, this is one of the most complicated systems in the body. Emma Bryce explains how the different parts of the digestive system work to transform your food into the nutrients and energy that keep you alive.
