We only have one digestive system and it's function is to convert food into energy that we need to survive and pack the residue for waste disposal. It is composed of:
Mouth - Chews the food
Esophagus - Receives food from mouth and transports it to theĀ 
Stomach - holds food while it is being mixed with enzymes
Small Intestine - breaks down food using enzymes produced by the pancreas and bile from liver
Large intestine - processes waste for easy bowel
Anus - last part of the digestive tract
