They will allow the blood vessels to widen so that more heat loss can occur through evaporation. This is vasodilation.

How do arterioles in the dermis respond to a cold environment?
Constrict
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.
Blood vessels in the dermis that carry oxygen and food?
Arteries to arterioles to capillaries where exchange occurs. Oxygen and nutrients are exchanged for carbon dioxide and wastes.
Free nerve endings within the dermis that are activated by hot and cold temperature?
Thermoreceptors
What are the two layer of the dermis?
The papillary and reticular dermis are the two layers of Dermis.
What causes you to sense cold air around you?
encapsulated endings
What layer of dermis is below the epidermis?
The Papillary Layer which is a part of the Dermis
What was the inuit's environment like?
there environment was dry and cold very very cold.
What blood vessel connects arteries to capillaries?
Arterioles.
What are cardiovascular adadptions?
incorporations of father arterioles by daughter arterioles
What layer of skin has nerves and blood vessels?
Also known as the subcutaneous layer or the sub-dermis. It is called Submucosa.
What is the superficial region of the dermis?
The papillary dermis is the most superficial layer of the dermis. Deep to it is the reticular dermis.
