Homeostasis in a Beaker of Water and Glucose levels in the Blood.

Try using a Bunsen burner to keep a beaker of water at 50 degrees.

This is a good example of negative feedback. The rise in temperature of the water causes you to do the opposite to the water and stop heating it. Thus it is a negative effect. Negative feedback. This process is responsible for many of the systems in the body which must stay the same. For example Temperature regulation. It also controls Glucose levels in the blood. 1) What effect does insulin hormone have on the muscles and the liver? 2) What hormone has the opposite effect? 3) What could cause the blood glucose level to increase? 4) When the glucose level rises in the blood, which hormone is released by the pancreas? 5) Where does the extra glucose go to? 6) What happens to the blood glucose level when GLUCAGON hormone is released by the pancreas? 7) What things cause the blood glucose level to fall? 8) Will people who are unable to make insulin have too much or too little glucose in their blood? 9) If there is too much glucose in the blood what effects might this have on the body? Draw a flow diagram to show how negative feedback controls the homeostasis of glucose in the blood. You must include the words; chemoreceptors, pancreas, liver, muscles, insulin, glucagons, glycogen, glucose, cell respiration.
