Thermoregulation Homeostasis
Thermoregulation homeostatic control system
Homeostasis is a mechanism which allows humans to maintain a stable internal environment despite fluctuations in the outside environment. It involves a control system that regulates body temperature, blood pressure, osmotic balance and levels of blood glucose.
Thermoregulation is the body’s ability to maintain a specific temperature (36.7 degrees) despite a rise or drop in temperature in the outside environment. If the human body temperature drops below 35 degrees hypothermia will occur, if the body temperature rises above 38.5 degrees then a person will become hyperthermic.
In order to maintain a stable body temperature thermoregulation uses negative feedback to counteract any changes in temperature. Negative feedback consist of three main components; A receptor, a control centre and an effector.
Homeostatic feedback control systems and usually cyclical involving, Input, Receptors, Controllers, effectors, output and feedback. Input is received from the internal or external environment which sends information to the receptors. The receptors are sensory nerves and organs. The receptors send the information to the controller which is …show more content…
This creates the potential of the thermoregulation control system breaking down and causing hypothermia. To counteract the dramatic drop in temperature the body will try to create heat by shivering which creates internal heat, contracting the blood vessels to decrease the blood flow to the skin keeping warm blood at the core and contracting the erector hair muscles to create an insulating hair layer. In extreme cold conditions adrenaline and thyroxin increase the energy releasing activity of the liver. If the thermoregulation control system is unable to get the body’s internal body temperature to a stable condition an athlete may become hypothermic resulting in death if hypothermia is left
