How is blood flow redirected to active muscles?

Answer 1

Your muscles need the blood to supply them with nutrients to help the be in the best condition, and oxygen so that they can create energy to work. So by the body sending blood to the right areas it will get things to the muscle that they need. Because your blood is warn sending it to the muscles during sport will help warm them up, this is a advantage for performers as it helps prevent injuries. This system is good for most sports other than short ones like sprinting as its only last a very small period of time so it's good for mainly aerobic sports like football or hockey. This is because it takes a time to get the blood flowing in a different direction so if the event is only going to last 10 seconds it's not needed that much.

Answer 2

Blood supplies muscle tissues (just as does all other tissues of the body), with oxygen, nutrients, vitamins, minerals, enzymes, hormones, etc. Restriction of this supply affects the function of those cells, tissues, organs. Depending on the location of the muscles the result could be very serious, for example heart attack in case of blood flow restriction to the heart muscles. Additionally, efficient blood supply to the skeletal muscle can affect the insulin uptake, as well. Decreased insulin sensivity might be traced to insufficient blood supply to skeletal muscle tissue.

Answer 3

Blood flow is redirected to active muscles during exercise. This is carried out under the direction of the sympathetic nervous system.
