Vasoconstriction And Vasodilation.
Vasodilation is when its hot, so your capillaries widen and your veins come up to the surface of your skin to release heat. as well as your pores widening releasing beads of sweat. (When it evapourates it cools your body down)
Vasoconstriction - when your veins and capillaries contract slighlty and dont stick up from your skin, to keep heat inside. As well as skin pours tightening, and your hair on your arms and stuff sticking up straight - to trap air in between to insulate your body. And if you start to shiver - its your muscles contracting and relaxing to produce heat energy.
What else can I help you with?
Can you live without capillaries?
A person can not live without capillaries. They help regulate body temperature, which is crucial to living. ~Charlotte~ =)
Do antlers help control body temperature?
No, antlers do not help control body temperature. Antlers are primarily used for display during mating season, establishing dominance, and defense. Body temperature regulation is mainly controlled by the animal's circulatory system and metabolic processes.
How does vasodilation help to control a persons body temperature?

What is an animal that relies on interaction with the environment to help it control body temperature known as?
An animal that relies on interaction with the environment to help control body temperature is known as an ectotherm. Ectotherms regulate their internal temperature by using external sources such as basking in the sun or seeking shade.
How do orangutans control body temperature they dont pant they have fur do they sweat?
Orangutans rely on behaviors such as seeking shade or water to help regulate their body temperature. They also have sweat glands on their palms and feet that help them cool down, although they do not sweat as much as humans. They may also adjust their activity levels depending on the temperature to help maintain their body heat.
How many valves capillaries?
Well the capillaries produce the more the body moves. If someone is running a marathon for example, the capillaries will start to reproduce to help get the blood moving. And capillaries dont have valves.
How do capillaries help control the amount of heat lost from the body?
They dilate at the surface of the skin to release heat into the atmosphere, and they can also constrict to reduce heat loss through the skin.
How do precapillary sphincters help regulate blood pressure and body temperature?
the Precapillary Sphincters control blood pressure and body temperature by regulating the flow of blood to the capillary bed.
Does the hypothalmus control body temperature?
Yes, the hypothalamus plays a crucial role in regulating body temperature. It acts as the body's thermostat by detecting changes in temperature and initiating appropriate physiological responses to maintain homeostasis. When the body temperature deviates from the set point, the hypothalamus triggers mechanisms such as sweating or shivering to help restore the optimal temperature.
How does your nerves control your body temperature?
The hypothalamus is responsible for some very important functions. One important function of the hypothalamus is the control of body temperature. The hypothalamus acts as a "thermostat" by sensing changes in body temperature and then sending signals to adjust the temperature. For example, if you are too hot, the hypothalamus detects this and then sends a signal to expand the capillaries in your skin. This causes blood to be cooled faster. The hypothalamus also controls the pituitary. The hypothalamus is composed of several different areas and is located at the base of the brain. Although it is the size of only a pea (about 1/300 of the total brain weight). Read more: How_do_nerves_control_human_body_temperature
What is a broken capillary?
Capillaries are the small blood vessels that carry blood to the almost all the tissue in the body. Broken capillaries are the reason you get bruises. So in other words, when you get a minor bruise, you have broken your capillaries. Happy to help!
Do feathers help vertebrates control their body temperature?
Do birds die? Well the answer is no, they don't. Birds have feathers, that's how they keep warm.
