Peripheral neuropathy affects the nerves in your toes, feet, legs, hands, and arms. Peripheral neuropathy may also cause muscle weakness and loss of reflexes, especially at the ankle, leading to changes in the way a person walks. Foot deformities, such as hammertoes and the collapse of the midfoot, may occur.
The vascular system, also called the circulatory system, is made up of the vessels that carry blood and lymph through the body. The arteries and veins carry blood throughout the body, delivering oxygen and nutrients to the body tissues and taking away tissue waste matter.
The vessels of the blood circulatory system are: Arteries. Blood vessels that carry oxygenated blood away from the heart to the body. Veins. Blood vessels that carry blood from the body back into the heart. Capillaries. Tiny blood vessels between arteries and veins that distribute oxygen-rich blood to the body. Blood moves through the circulatory system as a result of being pumped out by the heart. Blood leaving the heart through the arteries is saturated with oxygen.
