Nutrients
absorbed across the wall of the small intestine and into the capillaries or lacteal.
islets of Langerhans
Cells in the pancreas that secrete insulin
synthesis of plasma
The liver is involved in the ________ proteins e.g.
pyloric sphincter
a ring of muscle at the base of the stomach that allows chyme to pass into the small intestine in small amounts at a time.
oesophagus
a muscular tube that leads to the stomach.
alcohol
The drug, which if consumed too much, can also lead to inflammation, scarring and destruction of liver cells.
small intestine
The structure divided into three parts: the duodenum, jejunum and ileum.

Emulsification
The process where bile breaks up large fat droplets into smaller fat droplets
Villi
Finger-like projections on the inner wall of small intestines
Lacteal

Large intestine
has the function of absorbing the remaining water and mineral salts that have not been absorbed by the small intestine.
Rectum
where the waste matter is stored before it can be eliminated from the body through the anus.
Hepatic portal vein
A large blood vessel the blood capillaries of the villi converge into
Liver
The organ involved in the synthesis of plasma proteins
