The assortment of processes by which the body controls the internal environment making it constant is jointly known as homeostasis. In a bid to ensure that the body’s internal environment is stable, the conditions of the body must be continually monitored and adjusted through homeostatic regulation (Lenford and Johnson, 2015). It engages the receptor, the control center, and the effector.
The receptor detects information about changes that occur in the environment (Norris & Carr, 2013). They then send the information to the control centers, which interpret the information as either being below or above the homeostatic range (Clancy & McVicar, 2009). The control centers send commands to the effectors that correct the disturbance by either opposing or enhancing a stimulus thus reinstating homeostasis (Clancy & McVicar, 2009). This is a continuous process to ensure the continuity and maintenance of homeostasis. An example is where the temperature receptors in the skin detect a change in temperature; communicate this to the control centers which are in the brain, then to the effectors in the blood vessels and sweat glands facilitating the required adjustments (Lenford and Johnson, 2015).
When disturbances in the physiological balance occur, the system reacts to two forms of feedback. These include the positive and negative feedback. The majority of the homeostatic control mechanisms operate on the principle of negative feedback (Lenford and Johnson, 2015). It involves the system responding so as to reverse the direction of the change. An example of this principle is blood sugar regulation in the body. An increase in blood glucose higher than the homeostatic range triggers the processes that reduce it. Still, when blood glucose levels are below homeostatic range, the processes that increase the glucose levels will be triggered. Both instances result in the blood sugar level being maintained at a constant level
