The body system is requires consistent regulation in order to allow other functions to remain constant. Therefore, homeostasis as a biological function is tasked with regulation of the internal conditions to ensure that the human body is stable. On that account, as a medium of maintaining a dynamic range of environmental qualities, homeostasis possesses control mechanisms that have receptors of sensing stimulus. This means that information is sent to a particular control center that determines various stimuli that often elicit a change in organs, muscles, and other vital body structures (Szablewski, 2011). Therefore, instead of holding an internal environment within a given point, homeostasis has the potential of giving a negative feedback that reduces the activity of the organ systems and any other output. Regulation of blood pressure, for instance, is the operation of the negative feedback especially when it assists in the decrease of the heart rate through vasodilation.
However, with a set point instead of working range of temperatures, the body can get overworked. This is because the negative feedback mechanism is devoid of regulatory changes that respond effectively to the stimulus. Consequently, a homeostasis imbalance necessitates inefficiency and defective body control systems. A set point equally results to an internal environment with physical changes, risk of illnesses and aging that could destabilize the overall body system. Alternatively, a homeostatic imbalance creates a high concentration of salt in the blood system causing a decline of oxygen in the body. It, thus, generates a chain of homeostatic emotions that include thirst, breathlessness, and warmth (Wood et al., 2012). Likewise, a set point is retrogressive in the body system because it fails to restores vital ...Download file to see next pagesRead More

There are a wide number of changes that occur in the body. If these changes do not occur and the homeostatic mechanism keeps them at a set point for example body temperature which needs to be lowered or increased as per the changes in the external environment and if this temperature is kept at a set point, the body may not be able to survive at all.

For the purpose of this paper, we will be limiting the reference to humans as organisms. The search and removal of wastes inside the body which it produces, is called the process of excretion (Poison Protection). The major organs of excretion are the kidneys for urine elimination, the large intestines for expelling of solid wastes, the lungs for expelling carbon dioxide and water vapor, and the skin for eliminating salt and water through sweat.
