The three main functions of the stomach
Firstly, it acts as a place of storage, so that 2 or 3 meals a day can provide all our energy needs. Without this, we would have had to eat bits and pieces all day.
Secondly, it also aids the digestive process, as it is here that food is turned into a semi-liquid substance so that the nutrients can be absorbed from it.
A third very important function of the stomach is the destruction of contaminants that the food may contain – bacteria and other micro-organisms. Very little is absorbed into the bloodstream straight through the stomach walls – aspirin and alcohol being exceptions to this rule.
