For orthopedic surgeons, there is not. It is a rigorous examination that covers the medical and musculoskeletal aspects of sports medicine.

An artery usually carries pure, filtered and clean blood away from the heart, to all the parts of the body with an exception of the pulmonary artery and the umbilical cord. As the arteries move away from the heart, they divide into smaller vessels. These thinner arteries are called arterioles.
  Arterioles are very tiny arteries. In some areas of the body there are places where arteries and veins come together in tiny formations to swap oxygenated blood (in th â¦ e arteries) for unoxygenated blood (in the veins).rterioles are small diameter vessels that branch off of your arteries. They inevitably connect arteries to capillaries. You can find them pretty much anywhere in your body.
