[[File:DigestiveSystem.png|right|300px|thumb|A diagram of the '''digestive system'''.]]
The '''digestive system''' is an [[Organ System|organ system]] that breaks down food for [[Absorb (Biology)|absorption]] into the [[blood]].
===About The Digestive System===
: The '''digestive system''' breaks down food mechanically and chemically before [[Absorb (biology)|absorbing]] [[nutrient]]s into the [[blood]].
: The '''digestive system''' takes large [[insoluble]] [[molecule]]s and breaks them down into small [[soluble]] [[molecule]]s to be [[Absorb (Biology)|absorbed]].
There are several [[organ]]s in the '''digestive system''' you should know:
*[[Mouth]] - Breaks down food mechanically with [[teeth]] and adds [[saliva]] using the [[Salivary Gland|salivary gland]]s to make food easier to swallow.
*[[Oesophagus]] - Uses [[peristalsis]] to move food from the [[mouth]] to the [[stomach]].
*[[Stomach]] - Starts chemical [[digestion]] of food in an [[Acid|acidic]] environment.
*[[Liver]] - Makes [[bile]] to [[Neutralisation|neutralise]] [[Stomach Acid|stomach acid]] and break down [[fat]].
*[[Pancreas]] - Makes [[enzyme]]s to chemically [[Digestion|digest]] food.
*[[Small Intestine]] - [[Absorb (biology)|Absorb]]s food into the [[blood]] through [[villi]]
*[[Large Intestine]] - [[Absorb (biology)|Absorb]]s water from undigested food called [[faeces]].
*[[Rectum]] - Stores [[faeces]] before [[egestion]].
*[[Anus]] - A ring of [[muscle]] that holds [[faeces]] in.
