This is Anatomy and Physiology II related questions. More specifically on blood vessels. Please help me answer these questions, thank you :) List all the blood vessels a blood cell from the left fibula vein would have to go through to arrive in the right ulnar artery. There is no left brachiocephalic artery. How does the anatomy of the left side of the body differ from the right in this region? What type of tissue creates a valve? A piece of the great saphenous vein is removed from the leg and used to bypass clots that form in the arteries that supply the heart muscle. Why doesn't the leg suffer from the removal of a piece of this vein?
