Sheep Heart
Anterior Anterior longitudinal longitudinal sulcussulcus
Left AuricleLeft Auricle
Anterior Anterior longitudinal longitudinal sulcussulcus
You can find the anterior side of the heart by finding the auricle that you can see completely; it is the left auricle. The anterior longitudinal sulcus is on that side and the coronary sinus is on the posterior side.
Apex
What LAYER of tissue is this?
Apex
Myocardium (meaty areas of brown muscle)
Endocardium (inside all chambers where blood touches)
