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.
