The difference between nerves and blood vessels, nerves and blood vessels are two different concepts, but also two completely different organs, nerves are mainly for the human body to coordinate, command, which is divided into central and peripheral nerves of the two systems, such as the brain, the spinal cord is the central nervous system, as well as vegetative nerves, as well as our peripheral nerves are part of the nervous system. Blood vessels supply blood to various tissues and organs of the human body, and are distributed to all tissues of the body, divided into large vessels, medium vessels and capillaries. If the blood vessels are diseased, it will cause insufficient blood supply to the nervous system, inducing cerebral infarction, cerebral hemorrhage, chronic cerebral ischemia, and some serious cases will lead to dementia. So these two are different substances, but they are both related to each other.
