The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues.<\/b><\/i><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t Overview

\nWhat is the circulatory system? <\/b>
\n\nYour heart and blood vessels make up the circulatory system. The main function of the circulatory system is to provide oxygen, nutrients and hormones to muscles, tissues and organs throughout your body. Another part of the circulatory system is to remove waste from cells and organs so your body can dispose of it.

\n\nYour heart pumps blood to the body through a network of arteries and veins (blood vessels). Your circulatory system can also be defined as your cardiovascular system. Cardio means heart, and vascular refers to blood vessels.

\n\n Anatomy of the human circulatory system. <\/b>

\n\nThe circulatory system provides blood to all the body’s tissues so they can function.

\n Function
\nWhat does the circulatory system do? <\/b>

\n\nThe circulatory system\u2019s function is to move blood throughout the body. This blood circulation keeps organs, muscles and tissues healthy and working to keep you alive.

\n\nThe circulatory system also helps your body get rid of waste products. This waste includes:

\n\n
  • Carbon dioxide from respiration (breathing). <\/li>
  • \n Other chemical byproducts from your organs. <\/li>
  • \n Waste from things you eat and drink. <\/li><\/ul>\n\n How does the circulatory system work? <\/b>

    \n\nYour circulatory system functions with the help of blood vessels that include arteries, veins and capillaries. These blood vessels work with your heart and lungs to continuously circulate blood through your body. Here\u2019s how:

    \n\n1.\tThe heart\u2019s bottom right pumping chamber (right ventricle) sends blood that\u2019s low in oxygen (oxygen-poor blood) to the lungs. Blood travels through the pulmonary trunk (the main pulmonary artery).
    \n2.\tBlood cells pick up oxygen in the lungs.
    \n3.\tPulmonary veins carry the oxygenated blood from the lungs to the heart\u2019s left atrium (upper heart chamber).
    \n4.\t The left atrium sends the oxygenated blood into the left ventricle (lower chamber). This muscular part of the heart pumps blood out to the body through the arteries.
    \n5.\t As it moves through your body and organs, blood collects and drops off nutrients, hormones and waste products.
    \n6.\t The veins carry deoxygenated blood and carbon dioxide back to the heart, which sends the blood to the lungs.
    7.\t Your lungs get rid of the carbon dioxide when you exhale.

    \n\n\n\n Anatomy
    \nWhat are the circulatory system parts? <\/b>

    \n\nThe parts of your circulatory system are your:

    \n\n
    • Heart, <\/b>a muscular organ that pumps blood throughout your body. <\/li>
    • \n Blood vessels, <\/b> which include your arteries, veins and capillaries. <\/li>
    • \n Blood, <\/b>made up of red and white blood cells, plasma and platelets. <\/li><\/ul>

      \n\nWhat are the circulatory system circuits?

      \n\nYour circulatory system has three circuits. Blood circulates through your heart and through these circuits in a continuous pattern:

      \n\n
      • The pulmonary circuit: <\/b>This circuit carries blood without oxygen from the heart to the lungs. The pulmonary veins return oxygenated blood to the heart. <\/li>
      • \n The systemic circuit: <\/b>In this circuit, blood with oxygen, nutrients and hormones travels from the heart to the rest of the body. In the veins, the blood picks up waste products as the body uses up the oxygen, nutrients and hormones. <\/li>
      • \n The coronary circuit: <\/b>Coronary refers to your heart\u2019s arteries. This circuit provides the heart muscle with oxygenated blood. The coronary circuit then returns oxygen-poor blood to the heart\u2019s right upper chamber (atrium) to send to the lungs for oxygen. <\/li><\/ul>

        \n\n What are the types of blood vessels? <\/b>

        \n\nThere are three main types of blood vessels:

        \n\n
        • Arteries: <\/b> Arteries are thin, muscular tubes that carry oxygenated blood away from the heart and to every part of your body. The aorta is the body\u2019s largest artery. It starts at the heart and travels up the chest (ascending aorta) and then down into the stomach (descending aorta). The coronary arteries branch off the aorta, which then branch into smaller arteries (arterioles) as they get farther from your heart. <\/li>
        • \n Veins: <\/b> These blood vessels return oxygen-depleted blood to the heart. Veins start small (venules) and get larger as they approach your heart. Two central veins deliver blood to your heart. The superior vena cava carries blood from the upper body (head and arms) to the heart. The inferior vena cava brings blood up from the lower body (stomach, pelvis and legs) to the heart. Veins in the legs have valves to keep blood from flowing backward. <\/li>
        • \n Capillaries: <\/b>These blood vessels connect very small arteries (arterioles) and veins (venules). Capillaries have thin walls that allow oxygen, carbon dioxide, nutrients and waste products to pass into and out of cells. <\/li><\/ul>\n\n What are the circulatory system organs? <\/b>

          \n\nYour heart is the only circulatory system organ. Blood goes from the heart to the lungs to get oxygen. The lungs are part of the respiratory system. Your heart then pumps oxygenated blood through arteries to the rest of the body.

          \n Conditions and Disorders
          \nWhat conditions affect the circulatory system? <\/b>

          \n\nMany conditions can affect the health of your circulatory system, including:

          \n\n
          • Aneurysms: <\/b>Aneurysms occur when an artery wall weakens and enlarges. The weak spot can bulge as blood moves through the artery. The weak spot may tear, causing a life-threatening rupture. Aneurysms can affect any artery, but aortic aneurysms, abdominal aortic aneurysms and brain aneurysms are the most common. <\/li>
          • \n High blood pressure: <\/b> Your arteries work hard to circulate blood throughout the body. When the pressure (force of blood against the blood vessel walls) gets too high, you develop high blood pressure. When the arteries become less elastic (stretchy), less blood and oxygen reaches organs like the heart. High blood pressure puts you at risk for cardiovascular disease, heart attacks and strokes. <\/li>
          • \n Plaque deposits: <\/b> High cholesterol and diabetes can lead to fat and other substances collecting in the blood. These substances form deposits called plaques on artery walls. This condition is atherosclerosis, or narrowed or hardened arteries. Atherosclerosis increases the risk of blood clots and strokes, coronary artery disease, peripheral artery disease (and other artery diseases), heart attacks and kidney disease. <\/li>
          • \n Venous disease: <\/b>Venous diseases tend to affect veins in the lower body. Problems like chronic venous insufficiency and varicose veins occur when blood can\u2019t flow back to the heart and pools in leg veins. Deep vein thrombosis (DVT), a blood clot in the legs, can lead to a life-threatening pulmonary embolism. <\/li><\/ul>

            \n\n Care
            \nHow can I prevent circulatory system problems? <\/b>

            \n\nThese steps can protect the health of your circulatory system:

            \n\n
            • Aim for at least 150 minutes of physical activity every week. <\/li>
            • \n Eat a heart-healthy diet rich in vegetables and fiber and low in saturated fats and processed foods. Consider a Mediterranean-style diets or plant-based diet, as they appear to be the most heart healthy. <\/li>
            • \n Find healthy ways to ease stress. <\/li>
            • \n Maintain a healthy weight. <\/li>
            • \n Manage conditions like diabetes, high blood pressure and high cholesterol. <\/li>
            • \n Get help to quit smoking. <\/li><\/ul>

              \n\n Frequently Asked Questions
              \nHow big is the circulatory system? <\/b>

              \n\nYour body has more than 60,000 miles of blood vessels that circulate about 1.5 gallons of blood every day.

              \n What is red blood and blue blood? <\/b>\n\nAll blood is red. Hemoglobin, an iron-rich protein in red blood cells, mixes with oxygen to give blood its red color. Blood that\u2019s rich in oxygen is known as red blood.

              \n\nYour veins carry oxygen-poor blood. This is sometimes called blue blood because your veins can look blue underneath the skin. The blood is actually red, but the low oxygen levels give veins a bluish hue.

              \n Do arteries always carry oxygenated blood? <\/b>

              \n\nFor the most part, yes. The exceptions are pulmonary arteries and veins. Pulmonary arteries carry deoxygenated blood to the lungs. Pulmonary veins return the oxygenated blood to the heart.

              \n\n A note from Cleveland Clinic<\/b><\/i>

              \n\nYour circulatory system plays a critical role in keeping you alive. Blood vessels carry blood to the lungs for oxygen. Then your heart pumps oxygen-rich blood through arteries to the rest of the body. Your veins help your body get rid of waste products. Conditions like high blood pressure, high cholesterol and atherosclerosis can affect the health of your circulatory system. If you have one of these conditions, talk to your healthcare provider about steps you can take to protect your cardiovascular health.
