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.

A person can not live without capillaries. They help regulate body temperature, which is crucial to living. ~Charlotte~ =)
yes.

An exotherm.
the Precapillary Sphincters control blood pressure and body temperature by regulating the flow of blood to the capillary bed.
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.
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.
The cardiovascular system(CVS) is an organ system that passes nutrients, gases, hormone,blood cells etc. to and from cells in the body to help fight diseases and help stabilize body temperature and pH to maintain homeostasis.The CVS comprises of:ArteriesVeinscapillariesHeartlungsspleenlivervanacava
Do birds die? Well the answer is no, they don't. Birds have feathers, that's how they keep warm.
1. sweat gland: the evaporation of the sweat from the surface of the skin maintains a constant body temperature. 2. blood capillaries: vasodailation or vasocontriction is also responsible for the temperature regulation.
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!
Shivering is the involuntary contraction and relaxation of your muscles. When muscles contract they use energy, which is released by 'burning' sugar. Some of the energy which is released escapes as heat and this raises the temperature of the body.
