surface area of the food for enzymes to
work on so they can work faster
Proteases, carbohydrases and lipases are added to the food here
Proteases break down ......................... into ........................

Produces a thick layer of mucus which coats
the walls of this organ and stops it being
digested by the acid and the enzymes
Muscular bag that churns up food. Contains

Produces proteases, lipases & carbohydrases which are released into the small
intestine
All of the food which cannot be digested travels through here. Water is
reabsorbed into the blood leaving faeces.
..................... Is added to the small intestine to neutralise the acid coming from the
stomach. Thus creates the ........................ pH for enzymes in the small intestine to work at.
If this did not happen, the pH would be too low and enzymes would get
...............................It also emulsifies fats into small droplets (breaks up large drops of fat
into smaller drops). This increases the ....................... ................... of the fats for lipase
enzymes to work on. This means fats can be broken down into .............. and ...................
more quickly
Food is mixed with saliva which contains the
enzyme .................... This breaks down

Digested food passes from the small
intestine into the blood. The small intestine
is adapted for this process by having
........................ which increase the surface
area for absorption
Food passes down this to the stomach. It has
muscles in its wall that squeeze in behind
food to push it along. This is called
