How food is broken down during digestion
Food is required by humans to grow and survive, and to provide 'fuel' for the energy needed in our biological reactions.
As opposed to plants that can acquire their food from soil and sunlight, animals are required to eat foodstuffs in order to create the energy they need to survive. These foods contain many compounds and elements that are useful to our body and our daily functions.
This food is entered into the body via the mouth, where the enzymes begin to breakdown the food while it is chewed. When this food is broken down into smaller pieces it can then be swallowed, where it travels down the oesophagus towards the stomach.
The stomach then continues to break down the foodstuff. The stomach at this point is filled with a type of acid that further breaks down the food, until it is in a semi-liquid state. Note that the stomach only acts as a storage point at this stage, until the food slowly passes into the duodenum, which is part of the small intestine.
