Exam 1 Review - Heart Flashcards
In right coronary dominance, what artery is a branch of the circumflex artery?
Obtuse marginal artery
The outflow tract of the right ventricle, or the “conus arteriosis” is similar to what structure in the left ventricle?
Aortic vestibule
What chamber of the heart is in contact posteriorly with the esophagus?
The left atrium (through the oblique sinus and pericardium).
In left coronary dominance, the left coronary artery, by way of the circumflex branch, gives rise to what artery?
The posterior interventricular artery
In the right ventricle, what structure separates the inflow/outflow tracts of the heart?
Supraventricular crest
Which major artery of the heart supplies the right atrium, most of the right ventricle, and part of the left ventricle?
Right coronary artery
Which major artery of the heart supplies the SA and AV nodes (MOST of the time)?
Right coronary artery
The artery that supplies the ____________ artery determines coronary dominance.
Posterior interventricular artery (Posterior descending artery, PDA)
*NOTE: Some sources read AV nodal artery as the artery that determines dominance.
If the posterior descending artery is supplied by the circumflex artery, the heart is classified as ______ dominant.
Left coronary dominant
