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.
Your pulmonary veins are a group of blood vessels that drain oxygenated blood from your lungs and return it to your heart. The word 'pulmonary' comes from the Latin root 'pulmo,' meaning 'of or relating to the lungs.'.ulmonary Vein Function. The basic function of your pulmonary veins mirrors that of other veins in your body: they transport blood back to your heart. However, unlike all of the other veins in your body, which ultimately deliver deoxygenated blood to your heart, the pulmonary veins carry oxygenated blood to your heart.
