Venipuncture
The arteries are situated in protected grooves and canals formed by bones, muscles, and fasciae, which protect the vessels from compression and injury. Since the dorsal side of the bodies of four-legged animals is unprotected, in the process of evolution the vessels became located on the ventral side. This position was preserved in human beings, which explains the position of the aorta and its branches in front of the spine and of the arteries of the neck and extremities mainly on the anterior surface of the body. There are no large arteries on the back.Medical Coding Services
