Your circulatory system is made up of your heart, blood, blood vessels and lungs. In your circulatory system your heart pumps blood transporting nutrients, water and oxygen to your bodys cells. Your circulatory system allows your lungs to rid the body of waste and carbon dioxide and bring oxygen into your blood.
Exercise and healthy eating are two ways you can help keep your circulatory system healthy. Smoking does damage to healthy blood circulation. When you smoke the carbon monoxide and nicotine entering your body have negative effects on your blood and blood vessels and constrict circulation.
Signs of poor circulation include cold hands and feet, numbness, dizziness, migraines, varicose veins and pain in your feet or legs. Consult a doctor if you have these symptoms. Untreated, poor circulation can lead to stroke, high blood pressure, kidney damage and other diseases. Less
