3 Tissue Layers of Heart: (Outer Surface) (Inner Surface)

Myocardium: Cardiac Muscle

Heart surrounded by Heart

We studied the heart in lab. From that, you should know the following (questions will be on future lecture exams): 1. You should know all four chambers of the heart from both external and internal perspectives. 2.You should know all of the major blood vessels which carry blood into or out of the heart. 3.You should understand the pathway of blood flow through the different chambers of the heart and the major blood vessels noted in #2.

We studied the heart in lab. From that, you should know the following (questions will be on future lecture exams) - Continued: 4.You should know the coronary arteries (right, left, marginal, circumflex, anterior interventricular, posterior interventricular). 5.You should know the cardiac veins (small, middle, great; coronary sinus). 6.You should know where on the surface of the heart each coronary artery and cardiac vein is located: Which sulcus / groove it lies in Which other coronary artery or cardiac vein lies in that same sulcus 7. You should know from where blood is flowing into each of the coronary arteries, and to where blood is flowing in each cardiac vein.
