Booker Taliaferro Washington was an American educator, author, and adviser to multiple presidents of the United States. Complex organisms such as mammals have areas within the body that function best at vastly different pH levels. In essence, negative feedbacks preserve your body's original or 'set' condition and positive feedbacks do the opposite and change you body more by constantly pushing certain types of growth or development in the same direction until something has been accomplished. The pH value is important in maintaining homeostasis because it provides the correct balance of hydrogen ions in solution. The maintenance of the conditions by homeostasis is very important because in the wrong body conditions certain processes (osmosis) and proteins (enzymes) will not function properly. The many processes by which the body controls its internal environment are collectively called homeostasis. Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. When outside influences disrupt homeostasis, feedback loops return the variables back to normal levels.
