Draw a labelled diagram showing the interconnections between the liver, gall bladder, pancreas and small intestine.

Outline the role of glucagon in homeostasis of glucose.

List two examples of polysaccharides.

a. pancreas linked to small intestine by (pancreatic) duct (pancreas and small intestine both must be labelled);

b. gall bladder shown associated with liver and linked to small intestine by (bile) duct, (gall bladder and small intestine must be labelled);

c. showing (bile and pancreatic) ducts joined together before discharging in small intestine;

Ducts are to be drawn as double line structures.

a. (glucagon) released in response to low blood glucose levels;

b. (glucagon) increases blood glucose levels;

c. glucagon leads to conversion of polysaccharides/glycogen (in the liver) to glucose;

Do not accept implication that glucagon directly converts glycogen to glucose.

Award [1] for any two polysaccharides.

"Well I will just draw a diagram of the gastro intestinal tract and hope for the best", seemed to be the idea of many, resulting in no marks. The connection from the pancreas and the gall bladder to the small intestine had to be shown clearly as ducts, not random lines. The indecision manifested itself in the fact that many candidates drew very feint diagrams, resulting in scanning problems. Point 6.1.4 from the guide states that the interconnections should be clearly shown.

Most well prepared candidates could outline the role of glucagon.

A disturbing number could not name two polysaccharides.
