Homeostasis in mammals — practice question

Complete the passage by using the most appropriate scientific terms. Homeostasis, in mammals, is the process of keeping the .......................................... environment of the body in optimum conditions so that cells can function efficiently. Blood water potential, core temperature and blood glucose concentration are all factors that need to be kept at optimum values or set-point. When a condition deviates from its set-point, a corrective mechanism is triggered. An increase in blood glucose concentration triggers processes to decrease it and vice versa. This corrective mechanism is called ........................................... . The pancreas is involved in the control of blood glucose concentration. Glucose binds to ........................................... on the cell surface membrane of pancreatic cells. These are ........................................... cells, which secrete hormones such as insulin and glucagon. The two hormones have opposite effects on the blood glucose concentration. For example the action of one hormone stimulates the uptake of glucose by cells for respiration and the action of the other hormone stimulates the breakdown of ........................................... to glucose in the liver.
