If your body temperature gets too high, then one way that the body goes about lowering it, is to cause peripheral blood vessels to dilate, thus causing more blood to flow through these vessels, ie the vessels of the skin esp. This is why a light skinned person will appear flushed when they are very warm. Blood carries a lot of heat, so when blood rushes through these peripheral vessels near the skin surface, they will give up heat to the environment, thus cooling down the body. The reverse will happen in body temperature falls too much.
What else can I help you with?
The pressure of massage techniques stimulates the release of these hormones to vasodilate the blood vessels?
histamine
What does peripheral blood vessels mean?
Peripheral means "at the edge". The blood vessels further away from the heart.
If the temperature outside is a sweltering 41 degrees Celsius how is a human's body likely to respond to maintain homeostasis?
To maintain homeostasis in response to high temperatures, a human's body will likely increase sweating to cool down through evaporation, vasodilate blood vessels near the skin to release heat, and decrease metabolic rate in extreme cases to conserve energy. These responses help regulate body temperature and prevent overheating.
Peripheral vascular diseases are disorders of the blood vessels that are located outside of the heart and brain?
Peripheral vascular disease is disease of the blood vessels of the peripheries i.e. the limbs. Atherosclerosis, how ever is a generalised disease and other vessels are also involved
How does ear size help foxes maintain constant body temperature?
There are blood vessels in the ears that help maintain body temperature and the bigger the ear the more surface area it has to work with in order to regulate the temperature.
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.
What is the large peripheral blood vessels into which extra-embryonic blood vessels open?
vitilline vein
Contra indications for axillary temperature?
Skin disease. 2- Axillary operation. 3- Unconsciousness, shocked patients 4- Constricted peripheral blood vessels.
Which structures help maintain your body temperature?
Structures such as sweat glands, blood vessels, and the hypothalamus in the brain help regulate body temperature. Sweat glands release sweat to cool the body through evaporation, blood vessels dilate to release heat, and the hypothalamus controls these processes to maintain a stable body temperature.
When the temperature increases. what does the brain do to try to maintain a constant temperature?
In hot weather the brain causers the vessels to move close to the surface and dilate. In cold weather it causes the vessels to move away from the surface and contract.
What in tobacco constricts blood vessels?
Nicotine is the blood vessels' constrictor. Not all blood vessels, of course, but mainly the peripheral blood vessels, including the brain capillary blood vessels.
Name two factors that increase peripheral resistance?
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
