The process of homeostasis when body temperature rises too high is the following:
When temperature rises, the human body uses thermoregulatory mechanisms, aimed at dissipating heat and staying around its usual temperature of about 37 degrees Celsius.
Thermoregulation is composed of a series of elements that connect the central and peripheral nervous system, the central regulatory system is located in the hypothalamus in which there are two regions, posterior and anterior, which assume the functions of heat production and loss, respectively.
Changes in temperature provoke the neuronal response of skin receptors, as well as variations in blood temperature, which serve as a signal to the hypothalamus to give an adequate response.
Blood temperature serves as a stimulus to the hypothalamus, which responds with variations in autonomic tone and probably in endocrine function to maintain body temperature within its normal limits.
Thus, an increase in temperature perceived by the hypothalamus causes an autonomic response that consists of:
- An increase in sweating (heat loss through evaporation).
- A cutaneous vasodilation (by loss of heat by conduction and convection, by direct contact with the skin of the heat) and.
- A decrease in muscle tone (decrease in heat production).
As a whole, this system in charge of thermoregulation of the internal environment maintains the temperature around the regulated value.
Therefore, we can conclude that the set of mechanisms, known as thermoregulation, is aimed at maintaining the temperature of the body's conditions (homeostasis), so that no damage or errors occur in the functioning of the body.
