An Introduction to the Homeostasis System

Our bodies are entitled to a number of systems of feedback control that enhance their survival, Homeostasis system works to regulate the internal environment and maintain its stability and constant condition in the body of a living organism. The essay below refers to various control systems In reference to any life system parameter, an organism may be considered to be either a conformer or regulator. The conformers allow the environment to make decisions on the parameter and regulators concentrate on the maintenance of the parameter at a constant level.

All the control mechanisms of homeostasis are supposed to have a minimum of three independent components for the enhancement of the process of regulation.

These are the receptor, control center, and effectors. Reflex is one of the stimulus-response events: it is usually an unpremeditated and involuntary response to a certain stimulus. For example, human beings cover their bodies from direct heat such as the strong rays of the sun, The receptor of this mechanism is the skin of the person which detects changes in the environment.

The detected stimulus directs the receptor to signal for a change to the control center which is the mind of the person. The control centre then responds to the effectors who command the individual to cover his or her skin for protection from the strong rays of the sun. Fight and flight is another stimulus-response system.

This is used by the animals to respond to threats by discharge of sympathetic nervous system commanding the animal to either fight or flee for security.

For example when a Zebra sees a lion. the stress response becomes activated. The activation of the sympathetic nervous system provides intense muscular efforts for the animal to escape the danger, The eyes of the Zebra are the receptors that send the signal to the control centre which then commands the legs to run. The mechanisms of blood sugar regulation are also a system of feedback control. The levels of blood sugars are regulated through negative feedback for the maintenance ol homeostasis.

When the blood levels changes to dangerous levels, the alpha and beta cells acts to respond to the changes. These cells are the receptors, they send their srgnal to the liver which either reduces or increases the amount of glucose convened to glycogen thus regulating the amount of blood sugar. The homeostasis control system is the most essential in the maintenance of dependability in the internal environment. Although the changes in the environment of any living organism occur, the magnitude is expected to be unnoticed. The control mechanisms assure the security and comfort of any organism by detecting it signaling and acting towards the dangers.

Positive feedback, on the other hand, works to amplify and reinforce deviations from a set point. This mechanism is often involved in processes such as childbirth and blood clotting, where a positive feedback loop is required to achieve a specific outcome. The homeostasis system involves a number of different organs and physiological processes, including the nervous system, endocrine system, and immune system. These systems work together to maintain balance and stability within the body. Homeostasis is essential for the survival of organisms, as it ensures that the body's internal environment remains within a range that is compatible with life. Disruptions to the homeostasis system can lead to a variety of health problems, including dehydration, electrolyte imbalances, and metabolic disorders.
