Fetal Echo Workbook questions and
answers with solutions
atrioventricular node - ANSWER Area of cardiac muscle that receives and conducts the cardiac
impulse
bulbus cordis - ANSWER Primitive chamber that forms the right ventricle
foramen ovale - ANSWER Also termed fossa ovale; opening between the free edge of the
septum secundum and the dorsal wall of the atrium
left and right atria - ANSWER Filling chambers of the heart

septum secundum and the dorsal wall of the atrium
inferior vena cava - ANSWER Venous return into the right atrium of the heart along the
posterior lateral wall
main pulmonary artery - ANSWER Main artery that carries blood from the right ventricle to the
lungs
mitral valve - ANSWER Atrioventricular valve between the left atrium and the left ventricle
patent ductus arteriosus - ANSWER Open communication between the pulmonary artery and
the descending aorta that does not constrict after birth

wall of the left atrium
right ventricle - ANSWER Pumping chamber of the heart that sends blood into the pulmonary
artery
superior vena cava - ANSWER Vessel receiving venous return from the head and upper
extremities into the upper posterior medial wall of the right atrium
tricuspid valve - ANSWER Atrioventricular valve found between the right atrium and the right
ventricle
