Comments on Wall post by Emma Brett
Hi Dror,
Also for the question "Describe the route taken by nutrients in food on a plate to cells in the tissues, explaining the role of each part. Explain the roles of the digestive system (5 marks) and the cardiovascular system (5 marks) in your answer. " ... Does the cardio vascular system come into it once the food is broken down and absorbed into the blood?
Thanks,
Emma
Yes, exactly. This question asks you to describe the 'journey' a bite of food does from the mouth to the cell. So, part of it, once the food has its final break in the digestive system (small intestine), then it goes to the ....blood circulation (start via the capilaries in the intestine, to the liver, then to general circulation, the heart, then via arteries to cells around the body).
