  2. Artificial heart
  3. Pulmonary Trunk
  4. Coronary bypass
  5. Period of isovolumetric contraction
  1. a is located in the Pulmonary Trunk.
  2. b As contraction proceeds, ventricular pressures continue to rise, but no blood flows from the ventricles because all the valves are closed. because the volume of the blood in the ventricles doesn't change, even though the ventricles are contracting.
  3. c is a mechanical pump that replaces the heart.
  4. d is an artery that exits the heart, carries blood from the right ventricle to the lungs.
  5. e is a surgical procedure that relieves the effects of obstructed coronary arteries.

5 True/False questions

  1. Plateau PhaseProlongation of the depolarization phase of a cardiac muscle cell membrane; results in a prolonged refractory period. A prolonged period of slow repolarization.


  2. Purkinje fibersThe inferior terminal branches of the bundle branches, are large-diameter cardiac muscle fibers. Modified cardiac muscle cells found beneath the endocardium of the ventricles. Specialized to conduct action potentials.


  3. End-systolic volumeThe volume is decreased to 50-60 mL.


  4. Superior Vena CavaVein that returns blood from the head and neck, upper limbs, and thorax to the right atrium.


  5. Foramen ovaleis a slight, oval depression on the right side of the septum marking the former location of the foramen ovale.
