Question

Anatomy Tutorial: Internal Anatomy of the Heart

Answer 1

note: I will be focusing on the location, rather than the functions, of these structures, for memorization purposes

Answer 2

then we'll label the pulmonary arteries and the pulmonary veins (notice that the pulmonary arteries are above the veins on either side)

Answer 3

it's not clear on this diagram, but two circular structures in the right atrium are the fossa ovalis and the opening of the coronary sinus. around the right atrium are the pectinate muscles

Answer 4

between the atria is the interatrial septum, and protecting the entry to the aorta is the aortic valve

Answer 5

similarly, the entry to the pulmonary artery is controlled by the pulmonary valve

Answer 6

the main chamber leading up the left pulmonary artery is the conus arteriosus
the cusp of the right AV and left AV valves also get their own label
the stringy parts are the chordae tendinae

Answer 7

attached to the chordae tendinae are the papillary muscles and below them are the trabeculae carnaea
near the apex of the heart is the moderator band
