How does vasodilation in the dermis decrease body temperature?
Wiki User
∙ 12y ago
Dermal vasodilation is a smooth muscle action triggered by the autonomic nervous system (and in particular the hypothalamus) when the body's temperature is raising. As the dermal blood vessels dilate (plump-up) with warm blood, heat is lost through the skin by radiation, convection and conduction.

Blood vessels in the dermis aid in the regulation of?
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.
Does vasodilation raise or lower body temperature?
vasodilatation reduces body temperature.
Is dermal blood supply part temperature regulation?
Yes. The body can increase blood flow to the dermis where heat will be lost or it will decrease flow to conserve heat.
What do arterioles in the dermis do in a cold environment?
They will allow the blood vessels to widen so that more heat loss can occur through evaporation. This is vasodilation.
What stimulates vaso dilation?
Vasodilation is a mechanism for thermoregulation . It is used for cooling down body temperature . Increased body temperature stimulates vasodilation .It results in increased blood flow to skin to aid heat dissipation .
What is the importance of negative feedback in the control of vasodilation and vasoconstriction?
Vasoconstriction and Vasodilation are a part of a body negative feedback, in which the body tries to restore homeostasis. Homeostatis is the function of keeping the internal body at it's general temperature (37 degrees Celsius). Without the negative feedback of Vasoconstriction and Vasodilation, the body would either be at a very low or very high temperature and this high/low temperature could cause death.
How does vasodilation help to control a persons body temperature?

How can you decrease the entropy of static body?
You can decrease the entropy of a static body by reducing the temperature.
Describe how the arterioles in the dermis respond to heat cold and stress?
Arterioles dilate in warm environments (vasodilation). Dilate means to open. Vasodilation is a process in which the increased blood flow through the dermis brings excess heat close to the body surface to be radiated to the environment. Arterioles constrict in cold environments (vasoconstriction). Constrict means to close. Vasoconstriciton is a process in which the decreased blood flow through the dermis keeps heat within the core of the body. Both take place to maintain homeostasis. In stressful situations, vasoconstriction takes place. It will shunt in the dermis or redirect blood to more vital organs such as the muscles, heart and brain.
A gland located in the dermis of the skin that helps to regulate body temperature is the?
Sweat glands
Does heat affect blood pressure?
Increases in body temperature cause a corresponding increase in respiratory rate and heart rate because there is an increase in metabolic needs of the body. As regards blood Pressure, I believe the blood pressure goes down as a result of an Increase in body temperature. The body generates a lot of heat that decreases body hydration level and a result the body becomes dehydrated and the BP decreases. Increase with fever, necessitating more oxygen. The client who has a decrease in body temperature will experience a decrease in respiratory rate, Heart rate and Blood pressure.
Do medication affect body temperature?
Some medication may affect body temperature. It can increase or decrease body temperature. I.e. tylenol may decrease temperature if you have fever. Some stimulant may increase temperature when used, etc.
