I will illustrate my answer with an example of the external temperature decreasing:

Thermoreceptors in the skin detect the change in environmental temperatures, nerve impulses are sent via the autonomic nervous system to the hypothalamus. The hypothalamus monitors the temperature of the blood running through it, the hypothalamus will then send nerve impulses to the heat gain centre in the posterior hypothalamus ( Co-ordinator). Nerve impulses are then sent to the skin (effector). There are a number of mechanism that occur to conserve heat. Vasoconstriction may occur, this is where the shunt vessel dilates allowing the arterioles to constrict and the blood flow is reduced to the surface capillaries. Most of the blood flows under an insulating layer of adipose tissue, this prevents heat being dissipated to the environment via conduction. Sweating is also reduced. Shivering also occurs, these are involuntary rhythmic contractions that help generate metabolic heat. The rate of respiration is also increased. The pilli erector muscles are stimulated, causing hairs to be raised, this traps an insulating layer of air.

Homeostasis: refers to the constant internal temperature mantained for all the cells of the body.a homeostatic mechanism and a negative feedback system


Homeostatic Mechanism maintains a healthy body. And so it occurs in various processes


A homeostatic mechanism is the property of a system, either open or closed, that regulates its internal environment and tends to maintain a stable, constant condition. For example: the hypothalamus (which is a homeostatic mechanism) senses when your body's temperature is too high or too low. In a situation where the temperature of your body is above normal, the hypothalamus senses that a change needs to be made in order to reverse the heating of the area and reduce the amount of blood that is sent to the location. In turn this action will cool the body and return it to the normal temperature in which it should be maintained.


Examples of homeostatic mechanisms in the body include:internal body temperature regulation,blood-glucose levels,water and ion concentration in the body.


The importance of homeostatic regulation is great to the effect that without it our body wouldn't be able to keep all of its organs in sync and working in a orderly fashion



Homeostatic regulation is controlled in the body by the autonomic nervous system and seeks to maintain relatively stable conditions in the internal environment. The main gland of homeostasis is the hypothalamus and the major organ of homeostasis are the kidneys.


Regulation of body temperature, or thermoregulation, is the ability of some organisms to keep their body at a stable temperature. Thermoregulation is a part of the overall body regulation process known as homeostasis.


Homeostatic regulation of our core body temperature is important because the enzymes that perform metabolic reactions will function less effeciently and eventually cease to function if not kept at the proper temperature(37 C)


The processes and activities that help to maintain homeostasis are referred to as homeostatic mechanisms. for example regulation of blood pressure, regulation of pH in the body fluids and regulation of blood glucose levels.



Homeostasis is the maintenance of equilibrium within the body including body temperature. The medulla is the primary control center for homeostasis in the brain. The carotid sinus is another primary mechanism for homeostatic control and it contains baroreceptors which maintain blood pressure which is important in maintenance of the body's temperature.


Homeostatis is the maintenance of constant conditions in the internal environment of the body despite large swings in the external environment. For example, when the external temperature drops, the body's mechanisms create body heat in an attempt to keep the internal temperature within a suitable range.


Homeostatic mechanisms return the body to its normal state. Most of these are controlled by negative feedback.


Skin participates in homeostatic regulation of body tempertures through sweating with evaporation cooling, and adjusting blood flow in the dermis. It keeps in your body heat and regulates the temperature. It keeps in your body heat and regulates the temperature.


Urinary fluid is body temperature. Humans are homeostatic...their body temperature is 98.6 on average...the average temperature of urine in the bladder is therefore about 98.6.


No. A spider has no mechanism to maintain its body temperature.


Homeostatic mechanisms for regulation of breathing rate The body is mainly automatic for the rate of ventilation and does not notice minor variations that are the result of homeostatic regulations. An individual is only controlling their own breathing when holding their breath, speaking or taking deep breathes. When the body's metabolism produces extra carbon dioxide breathing rates increase slightly until it is blown out of the body in expiration. If a period of forced ventilation such as gasping is presented to the body it will lower the carbon dioxide levels in the body and homeostatic mechanisms will slow or stop breathing until levels return to normal.


The hypothalamus is responsible for the regulation of temperature in organisms. It is important because temperature directly affects vital biochemical processes within the body. Without a regulating mechanism, the organism will die.


regulation of body temperature


Regulation of body temperature.


The scrotum is the body part is used when the temperature regulation is essential to the production of sex cells.


Blood vessels in the dermis of the skin aid in the regulation of body temperature by constricting (vasoconstricting) to maintain internal body temperature, or expanding (vasodilation) to release heat and lower body temperature.


i think the only homeostatic mechanism which works at it's best during exercise is the osmotic mechanism of the kidneys we lose water as sweat during exercise and hence kidneys have to work to retain the water in our body.


Body temperature regulation is a problem in premature infants because they lack sufficient body fat for insulation. Also, the hypothalamus is not yet fully functional.
