Homeostasis is a natural response in which the body systems work together in order to keep the internal environment of the body at a constant rate despite changes in the external surroundings. Homeostasis involves the maintenance of many different controllable things within the human body. This includes; oxygen levels, blood pressure, carbon dioxide levels, pH, water levels, hormones, body temperature and glucose levels. All of these things remain at a constant regulated rate even when there are changes in the external environment to the body. All of the body's cells and tissues are used for homeostasis. The changes which occur in the outside environment are detected by receptors and when certain changes are detected the body initiates the appropriate response. A homeostatic response can either be a behavioural change or physiological changes.
For example; when our body temperature decreases we put on extra clothes in order to become warmer and increases out temperature. This would be an example of a behavioural response to changes in the outside environment.
A physiological response to changes in the environment would be when our blood glucose levels decrease due to the release of insulin and glucagon is then released in order to maintain these levels. The release of glucagon in the body results in the release of glucose by the body’s cells.
The body responds to changes in the external environment in many different ways. Some examples of homeostatic responses would be a change in
