Question 11

What is the process of mono gastric digestion

Answer 11

Food is mechanically broken down by the teeth

saliva is added which contains amylase which starts chemical digestion

the food is swallowed and travels down the oesphagus via peristalsis.

Enzymes and hydrochloric acid is added in the stomach

food enters the duodenum and mixes with bile which emulsifies fats and enzymes from the pancreas.

Nutrients are absorbed in the jejunum and ileum, then water is absorbed via villi in the large intestine.

waste is stored in the rectum and leaves the body by the anus.
