o The digestive system breaks down larger
food molecules into smaller molecules
which can be absorbed into the blood
stream.

, Functions
o Oesphohagus – a muscular tube that
pushes food down into the stomach.
o stomach – squeezes and relaxes to mix
food with gastric juices and acid to break it
down.
o Small intestine – absorbs nutrients and
water from food.
o Villi – digested food is absorbed into the
blood through the wall of the small intestine.
o Large intestine – water and salts are
absorbed from undigested food, and it
becomes nearly solid.
o Rectum – where faeces is stored.
o Anus – where faeces pass out of the body.
o Liver – produces bile, converts glucose into
glycogen and stores it, stores iron and
vitamins, detoxifies blood.

break down fat and neutralizes acid from
the stomach.

glucagon, and releases digestive enzymes
which continues to digest food.
