Mechanical digestion happens here- your jaw action.
A bolus is created; this is a ball of food covered in saliva. This is help full as the food is lubricated to enable swallowing and enzymes in the saliva can begin to break down the food. (amylase)
this tube connects you mouth and stomach. It is next to the trachea which is covered by the epiglottis when you swallow so the food only enters the oesophagus.
Peristalsis- or muscular contractions- moves the food downward.
Churning mechanically digests whilst enzymes do so chemically.
Chyme is the name for liquid food existing in the stomach.
The small intestine
This absorbs digested molecules into the blood stream.
Villi cover the inside giving it a large surface area which many molecules can diffuse through into the blood.
This absorbs water from undigested food, producing faeces.
This produces the enzymes lipase, amylase and protease.
