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.
Your blood is pumped around by the heart which is the main function in your circulatory system. The heart sends blood through your blood vessels. The circulatory system consists of the heart, blood vessels, lymph, blood, and the lymphatic vessels and glands.
One primary function of the circulatory system is the transport of oxygen from the lungs to the cells. This is why the system has two basic parts: the pulmonary circulation, which takes blood to the lungs to pick up oxygen, and systemic circulation, which takes the oxygenated blood throughout the body.
