where is the sinus venarum
(Smooth Surface) right below the pectinate muscle, also on the flap of the right atrium, a smooth light colored parabola shape
where is the opening of the coronary sinus
(Space) the tiny hole on the inside of the right atrium, right below the fossa ovalis
where is the opening of the superior vena cava
(Space) on the boot heart, the probe will be put through the large canal going through entire heart, the top part
where is the opening of the inferior vena cava
(Space) on the boot heart, the probe will be put through the large canal going through entire heart, the flat back side
where is the left atrium
(Chamber) the top left side of the heart
where is the left auricle
(Feature) the flap on the left atrium, looks like an elephant ear with fingers on the medial side
where are the openings of the pulmonary veins
(Collective Space) when the probe is going through 2 holes on the top of the heart on the posterior side

(Portion) the top thin part of the interventricular septum
where is the right ventricle
(Chamber) the bottom right side of the heart
where is the right atrioventricular orifice
(Space) the probe will be put through the entire right side on the heart from the atrium down to the ventricle
where is the tricuspid valve
(Feature) inside of the right orifice, little flaps with a lot of stringy bits in between
where are the papillary muscles
(S) the 3 bulbs on the bottom left side of the right ventricle, the carrot part
where are the tendinous cords
(Feature) the strings coming off of the papillary muscles on the bottom left side of the right ventricle, the green leaf on top of the carrot part
