trabeculae carneae
papillary muscles

finger like muscles in ventricles attached to chordae tendineae
what structure attaches to papillary muscles in ventricles and is white in color?

chordae tendieae

wall between ventricles?

interventricular septum
why is the Left ventricle 5x thicker then right ventricle?

because the right ventricle only has to pump blood to lungs, and the left ventricle has to push blood throughout body and so it needs to be stronger and use more force to get blood where it needs to go

where are aortic semilunar valve and pulmonary semilunar valve locate?
- aortic semilunar leaves heart leading into aorta
- pulmonary semilunar leaves heart into pulmonary trunk
front of heart vs back of heart?
- anterior view
- pulmonary trunk is visible
- ascending aorta is visible
- posterior view
- 4 pulmonary veins attached
when blood backflows what is it called?

regurgitation
