  • How many pumps is the heart made of?

  • What does the right pump of the heart do?
    forces deoxygenated blood to the lungs where it picks up oxygen and loses carbon dioxide
  • What does the left pump do?
    pumps the oxygenated blood to the rest of the body, which needs a bigger force
  • How many chambers does the heart have ?
    4
  • What are the upper chambers of the heart called?
    the atria
  • Where does the right atrium receive blood from?
    the vena cava
  • Where does the left atrium receive blood from?
    the Pulmonary vein
  • Why do the atria contract together?
    to move blood into the lower chambers of the heart
  • What are the lower chambers of the heart called?
    The Ventricles
  • What happens when the ventricles contract?
    they force blood out of the heart
  • Where does the right ventricle push blood?
    into the pulmonary artery
  • Where does the left ventricle push blood?
    into the aorta
  • Which chamber of the heart has the thickest walls?
    The left ventricle
  • What do valves in the heart do?
    prevent the blood from flowing in the wrong direction
  • Label the Heart:
    A) Aorta
    B) Pulmonary Vein
    C) left atrium
    D) left ventricle
    E) right ventricle
    F) right atrium
    G) vena cava
    H) pulmonary artery
  • What supplies oxygenated blood to the heart muscle?
    the coronary artery
  • When does Coronary Heart Disease occur?
    when the coronary arteries become blocked or narrower due to a buildup of fatty material inside them
  • What can doctors use to open up the arteries
    a stent
  • Why is it important for the for the arteries to remain open?
    they allow the blood to deliver nutrients and oxygen to the heart muscles, allowing it to function.
  • What else can be used to replace damaged coronary arteries?
    Bypass surgery with lengths of vein
  • What drugs can be used to reduce the fatty buildup in arteries?
    Statins - lower the cholesterol levels
  • Label the stages of putting a stent into an artery:
    A) Stent and balloon
    B) Fatty deposits narrow artery
    C) Balloon inflated to open stent and artery
    D) stent holds artery open
