(Vellacott and Side 2002) There are several things that ingest to be regulated: 1. The bodys temperature. If temperature were allowed to rise erupt of control, protein and therefore enzyme, bodily structure would be take uped, perhaps with inglorious results. 2. The count of water supply within the body. The directs of water deal affect metabolism and osmosis. Again this tush have se rious consequences. 3. The amount of glucose in the body. This direct can also affect osmosis and simply the rate of respiration as well. 4. The amount of nitrogenous forsake in the body. Nitrogenous waste can become hepatotoxic in the body. It is important that this aim does not get besides high.

Negative feedback To regulate these things the body needs firstly to key the level and then to serve in an appropriate way. For temperature, water and glucose there is a level called the norm (e.g, normal body temperature is 36.9°C). If the level gets too high this triggers the body to lower it by sweat ing. If the level gets too low this triggers! the body to raise it by shivering. This is the belief of negative feedback. Positive feedback is when a high level of something triggers the body to increase it even further. The precisely example of this in the tender body is during pregnancy when the hormone oxytocin is released.
