The process of digestion is mainly in the stomach but lots of things are also digested in the small intestine e.g. maltose into glucose (enzyme used is maltase), protein into amino acids (protease is the enzyme) and lipids into glycerol and fatty acids (lipase is the enzyme) When these have been broken down they are absorbed through the lining of the small intestine where they are absorbed into the blood (absorbtion) and used as raw materials for growth and tissue repair (assimilation).
So the answer is the small intestine
Hope that helped =)

Movement that allows the food to travel downwards along the oesophagus?
PeristalsisPeristalsis is the rhythmic contraction of the gastrointestinal tract that moves food along the whole tract.
Which part of the gastrointestinal tract plays the greatest role in the absorption of digested food?

What does movement mean in reference to digestion?
the physical propulsion of food through the gastrointestinal tract (GI tract)
What is the alimentary tract?

What type of digestion is aided by the action of stomach muscles?
In the mouth, the muscle help the teeth in cutting and breaking the food particles. In the gastrointestinal tract, smooth muscles are present in the walls of the gastrointestinal tract ,and they help in the peristalsis which are the muscle contractions that produce the bowel movements which help in the movement of food (chyme) comming out of stomach into the intestines and through the intestines. Also, muscles help closing and opening the sphincters present throughout the gastrointestinal tract.
