Sorry my question is why do body cells need glucose? On your diagram explain the role of receptors, control center, and effectors? Hi Jamie.Why do body cells need glucose?Which system activated in response to elevated blood sugar level? See more questions like this: Draw a diagram to illustrate the role of negative feedback in homeostasis. The Islet of Langerhans is also known as the pancreatic islets. Please see the new Article: Glucose Regulation: Insulin and Glucagon I am having trouble figuring out which receptors are involved! Just need more detail in blood glucose regulation - also is there another name for the Islet of Langerhans? ![]() You will feel this in sweat.Ĭan you explain negative feedback steps for homeostasis of blood glucose levels including effector input/output etc? To try and decrease your temperature, your body will make changes to enable blood flow to the surface of your body and disperse the heat. This conversion produces a waste product: heat. When your body exercises is converts food into energy. Your body is trying to make more oxygen by pumping your heart harder and moving blood and oxygen away from non-working parts of the body to ones that are working hard. This need for oxygen also explains why the heart rate increases. Lactic acid build-up can inhibit your ability to exercise effectively. If too much carbon dioxide builds up during exercise it can lead to a build up of lactic acid during exercise. This increases your breathing rate and also releases carbon dioxide. When you exercise your muscles are working hard and your body works to ensure the right levels of oxygen are reaching your cells. How do these changes contribute to the maintenance of homeostasis?ĭuring exercise, your entire body works hard to maintain homeostasis. The brain responded to the demands of exercise by increasing respiration and heart rate. Want to join in? Click EDIT to write this answer. The skeletal muscles are also alerted by the hypothalamus that starts shivering to warm up the muscles and produce heat. It also sends signals to the sweat glands and as a result, these glands will stop secreting sweat. The blood vessels will start constricting to retain heat. The hypothalamus will send signals to the blood vessels. The receptors on the blood vessels, that detect these signals, are activated and transmit signals to activate the hypothalamus. When it is cold outside, our body temperature also drops (below 37✬). Both cases are not healthy for the body to function properly and can lead to problems and diseases. If this temperature decreases, it will result in hypothermia (low body temperature), and when it increases it will result in hyperthermia (high body temperature). The temperature of the body is around 37✬ at all times. Yes, homeostasis is important to keep everything in the body balanced. ![]() Describe the homeostatic feedback system that would be activated in response to a decreased external temperature See more questions like this: Why is blood temperature a negative feedback loop? An important aspect of homeostasis is maintaining a normal body temperature?Īn important aspect of homeostasis is maintaining a normal body temperature. We want to know the number of unique queries submitted.See more questions like this: Homeostasis feedback system respond to a decreased external temperature? The log is neither sorted by userid nor by time. The user 324325 searches for Tom Jones and visits Wikipedia for 1 second and then spends a lot of time on the official Tom Jones web site. Here, user 312121 searches twice for Britney Spears (different spellings) and later clicks on the Wikipedia link and spends 25 seconds on it. If the user clicked a URL, the log also shows the amount of time in seconds the user spent on the URL (the dwell-time).Ī concrete toy example of a query log is the following: The user either submits a query to the search engine (in which case query contains the query string submitted, otherwise this value is empty) or views a result list and clicks on a URL (stored in click, otherwise this value is empty). Where the userid is the IP address of the user and the timestamp is the time at which the action took place (in epoch). You have a search engine's query log of the form:
