co-ordinating homeostatic mechanisms’ (Human Body) whilst using feedback. If a change in condition is detected a corrective mechanism is activated‚ conditions return to set point and the corrective mechanism is then switched off. The conditions are then at constant level. Some of the factors controlled by homeostatic mechanism are: body temperature‚ blood glucose level‚ water content of the body‚ respiration and urea being carried by the blood. The changes within the homeostatic system is often

Vital organs that help to control the homeostatic mechanisms are the brain and nervous system. These vital organs help use to anticipate when key variables might rise and fall beyond the accepted range‚ for example; if it has been several hours since you have ate a meal and you are starting to

Homeostatic processes act at the level of the cell‚ the tissue‚ and the organ‚ as well as for the organism as a whole.

Homeostasis is the ’maintenance of equilibrium in a biological system by means of an automatic mechanism that counteracts influences tending towards disequilibria’. Homeostatic mechanisms operate at all levels within living systems‚ including the molecular‚ cellular‚ and population levels. in humans homeostasis involves the constant monitoring and regulating of numerous factors including‚ oxygen and carbon dioxide levels‚ nutrient and hormone levels and inorganic and organic substances.

In his film Supersize Me‚ he ate only food from McDonald ’s three times a day every day for a month. He consumed nearly twice the recommended amount of calories per day. Throughout the experiment‚ he experienced transient depression‚ sexual dysfunction‚ and in one instance a series of heart palpitations. At the end of
