We learnt how our food is digested, nutrients are absorbed and waste is disposed of in our bodies.
In the mouth, our teeth bite, tear and grind food into small pieces. The salivary gland produces saliva which helps moisten the food. It then travels down the oesophoagus into the stomach.
In the stomach, acid helps to break down the food even further.
Food then travels to the small intestine where nutrients are absorbed back into the body. The muscles in the large intestine push the waste along by contracting and relaxing until the faeces is excreted out through the anus.
