This is homeostasis maintaining a constant internal environment so what kind of things need to be kept constant in the body Well it's very important to keep our temperature the same at around thirty seven degrees Celsius you can find out more about this in the video on temperature regulation you also need to keep the levels of should be in the blood constant along with levels of ions and water your blood pressure needs to be carefully monitored along with him ounce of waste in the blood such as carbon dioxide and your ear . OK So let's say one of these factors goes to highlight what is the brain going to do to get it back to normal levels the answer to that is negative feedback negative feedback is the process but the brain uses either a hormone or nervous system to send a signal to the part of the body that can rectify the problem for example or to eat a meal with your blood sugar level increases you can see it on this craft this is detected in the pancreas will release a whole Michael insulin that causes the sugar to be stored in the. Therefore as you can see on the graph the blood sugar level returns to normal. Negative Feedback is the leap from which the body takes a stimulus. Cordoning and brings the body back to the normal levels so why is homeostasis so important on metabolism which is all the chemical reactions in a bodies that keep us alive is controlled by enzymes these enzymes only working pay specific conditions if these conditions. Change they could stop working and we could die lucky while this happens without you having to think about it we've had to go to supper it's been all day not just trying to keep all these things constant and we have no time to doing fun like watch videos of cats on the Internet.\n
