- Pulmonary Semilunar Valve
- Artificial heart
- Pulmonary Trunk
- Coronary bypass
- Period of isovolumetric contraction
- a is located in the Pulmonary Trunk.
- 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.
- c is a mechanical pump that replaces the heart.
- d is an artery that exits the heart, carries blood from the right ventricle to the lungs.
- e is a surgical procedure that relieves the effects of obstructed coronary arteries.
5 Multiple choice questions
- Which extend beneath the endocardium on each side of the interventricular septum to the apex of both the right and left ventricles.
- carry blood from the lungs to the left atrium.
- is a double-layered, closed sac that surrounds the heart. It consists of the fibrous pericardium and the serous pericardium.
- is a surgical procedure performed on valves that are so deformed and scarred from conditions such as endocarditis that they have become severely incompetent or stenosed.
- (visceral Pericardium), is a thin serous membrane that constitutes the smooth, outer surface of the heart. Also called the serous pericardium.
5 True/False questions
Plateau Phase → Prolongation of the depolarization phase of a cardiac muscle cell membrane; results in a prolonged refractory period. A prolonged period of slow repolarization.
Purkinje fibers → The 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.
End-systolic volume → The volume is decreased to 50-60 mL.
Superior Vena Cava → Vein that returns blood from the head and neck, upper limbs, and thorax to the right atrium.
Foramen ovale → is a slight, oval depression on the right side of the septum marking the former location of the foramen ovale.
