Being exposed to high altitudes, where there is less oxygen, can actually make blood become a little thicker over time because the bone marrow will produce more red blood cells, which carry oxygen, she said. This may help endurance athletes, she said, but it will not make them feel warmer. However, she said, âOur bodyâs ability to control temperature or thermo-regulate does involve blood circulation. In the cold, the small blood vessels on the surface of our body get smaller to keep warm blood deeper inside. In the heat, they dilate to release heat from the body. Over all, how warm or cold a person feels âhas more to do with our perception of temperature than with our actual temperature,â she said.
Because veins are carrying oxygen-poor blood back to the heart they have a much less strong blood pressure than arteries that carry blood from the heart. Arteries have to have thicker walls because of the greater pressure on them.So it is easier to use veins, and less dangerous.f someone were to try to draw blood from one of your arteries, it would literally squirt out every time your heart beats. Plus, arteries are typically deeper within your body than veins (veins are much easier to get to when taking blood). Source(s): Nursing major.
