    Study Notes

    Circulatory System Anatomy

    • The circulatory system is made up of the heart, blood vessels, and blood.
    • Continuously circulates blood throughout the entire body.
    • Arteries carry oxygen-rich blood away from the heart to the rest of the body.
    • Veins carry oxygen-poor blood back to the heart.
    • Capillaries connect arteries and veins to tissues.
    • The heart is about the size of a fist.
    • It's a muscle, divided into four chambers: two atria (receive blood), and two ventricles (pump blood).
    • Valves prevent blood from flowing in the wrong direction.
    • The heart has four valves: tricuspid and bicuspid (atrioventricular), and pulmonary and aortic (semilunar).

    Circulatory System Blood Vessels

    • Arteries carry oxygenated blood away from the heart.
      • The dorsal aorta carries blood away from the heart to the body.
      • Pulmonary arteries connect the heart to the lungs to supply blood with oxygen.
    • Veins carry deoxygenated blood and waste back to the heart.
      • Superior Vena Cava and Inferior Vena Cava
    • Capillaries deliver blood to tissues and take away byproducts.

    Circulatory System Blood Cells

    • Red blood cells (erythrocytes) contain hemoglobin transporting oxygen and carbon dioxide.
    • White blood cells (leukocytes) act as the body's defense mechanism.
    • Platelets (thrombocytes) help blood form clots.
    • Plasma carries red and white blood cells, platelets, waste products, and other substances.

    Circulatory System Physiology

    • The circulatory system has three main subsystems: pulmonary (lungs), coronary (heart), and systemic (body).
    • The pulmonary system circulates blood between the heart and lungs.
    • The coronary system provides nutrients to the heart itself.
    • The systemic system transports blood to the body's tissues.
    • Pulmonary arteries carry oxygen-poor blood to the lungs.
    • Capillaries in the lungs transfer oxygen to the blood and remove carbon dioxide.
    • Pulmonary veins carry oxygen-rich blood back to the heart.
    • Coronary arteries transport oxygen-rich blood to the heart tissues.

    Circulatory System Common Ailments

    • Cardiovascular disease, hypertension, deep vein thrombosis, sickle cell anemia, and hemophilia are common circulatory system ailments.
    • Coronary artery disease involves narrowing of arteries feeding the heart, potentially leading to heart attacks.
    • Stoke happens when a blood clot blocks a blood vessel or artery, or when a blood vessel breaks, in the brain.

    Circulatory System Risk Factors

    • High blood pressure, high cholesterol, smoking, drug use, obesity, physical inactivity, diabetes, stress, age, gender, race, and heredity are risk factors of circulatory system diseases.
    • High blood pressure is a silent killer, as high cholesterol can accumulate and harden/block blood flow.
