HOMEOSTASIS
Body systems act together to make a point that the body acts efficiently as a whole, with the brain as a command centre. “Homeostasis is derived from the Greek, homeo or ‘constant’; and stasis or ‘stable’ and means remaining stable or remaining the same.” (Wikipedia. 2013) It is the procedure by which the body keeps static surroundings in which cells, tissues, and systems can operate. If there’s an alteration happen, these procedures can stop, decompress or quicken. Homeostatic mechanism controls a lot of activities inside the body such as our heart rate, breathing rate, body temperature and, blood glucose.
“Negative feedback works rather like the central heating system of a building. If the temperature falls below the desired temperature, the thermostat will detect this change and send a message to the boiler to switch on. The heating comes on and the building warms up. When it reached the temperature set by the thermostat, the boiler gets a message to switch off. The heating will switch on again when the temperature drops below the thermostat setting.” (Haworth, et al. 2010 P.206) In order to maintain the interior surrounding at constant, homeostasis relies on feedback like these from the body.

The one that monitor oxygen concentration levels of the blood are the nerve cells in the aorta and carotid artery that forward messages on the respiratory centres. If the oxygen-concentrated blood drops down, a message is forwarded to the respiratory centres to increase the rate of breathing to bring levels back to normal. If the carbon dioxide-concentrated become too high, chemoreceptors forward messages to the respiratory centres to increase the breathing rate. Through this, the concentration of carbon dioxide is brought back to normal and the breathing rate then
