Use State the name for chemicals that are secreted by glands into the blood and that affect organs elsewhere in the body. State the term used to describe the organs that are affected by these chemicals. organs Listed below are a number of responses shown by the human body: A the amount of saliva produced increases B the concentration of blood glucose falls C the concentration of blood glucose rises D the pupils become smaller E the rate of heart beat increases Which two of these are responses to the release of adrenaline? 1. 2. Examiner’s Use shows the blood glucose concentrations of three different people, G, H and I, over a 48-hour period. blood glucose concentration/ arbitrary units 08.00 20.00 02.00 08.00 time of day I H G 14.00 20.00 08.00 14.00 day 2 day 1 02.00 Two of the people are diabetic. The pancreas of one of these produces small quantities of insulin. In the other, the pancreas produces no insulin. The third person is not diabetic. Using the information in and giving a reason for your answer in each case, identify the person without diabetes reason: the person who produces no insulin reason: Diabetes can be treated by injection of insulin. Insulin can now also be taken by breathing it in. Suggest how insulin taken by breathing it in enters the blood.
