  • often referred to as the "transportation" system of the body. (what does it transport?)
  • consists of the heart, blood vessels, and blood.

    Divided into 4 chambers:

    1. right atrium - receives blood from body cells
    2. right ventricle - receives blood from right atrium & pumps to pulmonary artery
    3. left atrium - receives oxygenated blood from lungs
    4. left ventricle - receives blood from left atrium & pumps to aorta

    systole - period of ventricular contraction

    Arrhythmias are abnormal heart rhythms that can be mild to life-threatening.

    diagnosed by cardiac monitors & electrocardiograms

    capillaries - connect arterioles w/ venules; allow oxygen & nutrients to pass through to cells and carbon dioxide & metabolic products to enter capillaries

    veins - carry blood back to heart
