Homeostasis What is homeostasis? Homeostasis is the mechanism in our body that regulates and maintains a stable and constant environment. This enables our body to respond to changes in the environment around us as. The homeostatic mechanisms in our body‚ observe and monitor conditions and will then make a judgment whether to change the way the body functions is order to adapt to the outside surroundings better. The main organs involved in homeostasis are; the brain‚ liver‚ skin and kidney’s.

P5. Homeostasis is the process by which a constant internal environment is maintained by our body. For instance‚ this means that in our body‚ temperature‚ blood sugar levels‚ etc must be kept within a narrow range even when we are in a freezing climate‚ or while doing vigorous exercise etc. All homeostatic control mechanisms have at least three interdependent components which are: The receptor responds to changes in the environment‚ for example‚ detects temperature change. Then‚ after the receptor

Homeostasis is the tendency of an organism or a cell to regulate its internal conditions‚ usually by a system of feedback controls‚ so as to stabilize health and functioning‚ regardless of the outside changing conditions. Humans use homeostasis to regulate control systems such as body temperature‚ osmotic balance‚ blood pressure‚ blood glucose and respiratory gases in tissues. This report will focus on thermoregulation‚ which is the ability of an organism to keep its body temperature within certain

AIDS (acquired immunodeficiency syndrome) is caused by HIV (human immunodeficiency virus). HIV is transmitted usually through unprotected sex with someone who is already infected‚ but it can also be transmitted through infected blood. The immune system is greatly affected by the disease. Once it enters the body‚ the virus recognizes a protein on helper T-cells‚ called CD4 (Cluster of Differentiation Antigen No. 4)‚ and it attaches onto that receptor to take over the CD4 cell. The result is a virus

P1: A person’s diet is the food they regularly consume‚ for example a high fibre diet contains a lot of fruit and vegetables. A nutrient is anything that nourishes a human or animal for example iron is a nutrient if someone is a vegetarian they don’t get a lot of iron so they have to take iron supplement tablets. A meal is a fairly large portion of food that is served and eaten for example a roast dinner which contains vegetables‚ meat and potatoes. A snack is a small amount of food eaten in between

Annie Stevenson Foundations of Social Psychology 9th October 2014 To what extent‚ if any‚ does the concept of de-individuation explain group behaviour? Group behaviour is inevitably a challenging element of social psychology to be explained. Although many theories and ideas exist surrounding group behaviour‚ the focus of this particular essay will be to explain the behaviour of groups through the concept of de-individuation. According to Diener in ‘The Psychology of Group influence’ (edited by Paul
