(114 cards)
The Aorta is distal to the Left Ventricle and Aortic Valve, travels superiorly as the very short _______ _______, turns to the left as the _______ ______ then travels inferiorly as the ________ ________ through the Thorax.
Ascending Aorta
Aortic Arch
Descending Aorta
The Descending Aorta goes through the Thorax as the _______ _______, then proceeds through the _______ _______ on the Thoracic Diaphragm and into the Abdomen (now as the Abdominal Aorta).
Thoracic Aorta
Aortic Hiatus
The Ascending Aorta is short and produces what arteries?
Right and Left Coronary A.
This branch off the Ascending Aorta travels anteriorly around the heart to the posterior aspect.
Right Coronary A.
What are the branches of the Right Coronary A.?
Sinuatrial Node A. Conus Branch Atrial Branch Right Marginal A. Atrioventricular Nodal A. Posterior Interventricular A. Right Posterolateral A.
This artery supplies the Sinuatrial Node and is a branch off the Right Coronary A. 60 percent of the time, and is off the Circumflex branch of the Left Coronary A. 40 percent of the time.
Sinuatrial Nodal A.
This artery is a branch off the Right Coronary A. and supplies the Conus Arteriosus.
Conus Branch
This artery is a branch off the Right Coronary A. and supplies the Right Atrium.
Atrial Branch
This artery is a branch off the Right Coronary A. and travels along the inferior border of the heart.
Right Marginal A.
This artery is a branch off the Right Coronary A. and supplies the Atrioventricular Node.
Atrioventricular Nodal A.
This artery is a branch off the Right Coronary A. and travels along the posterior aspect of the heart between the Right and Left Ventricles.
Posterior Interventricular A.
These are branches off the Posterior Interventriuclar A. and supply the Interventricular Septum.
Interventricular Septal Branches
This artery is branch off the Right Coronary A. and supplies the Left Ventricle.
Right Posterolateral A.
This branch off the Ascending Aorta travels superiorly around the heart to the posterior aspect.
Left Coronary A.
What are the branches of the Left Coronary A.?
Anterior Interventricular A.
Circumflex A.
This branch off the Left Coronary A. travels along the anterior aspect of the heart between the Right and Left Ventricles. It is most responsible for supplying the Atrioventricular Bundle as it passes through the Interventricular Septum.
Anterior Interventricular A.
2/3 of the blood supply to the conducting system of the heart comes from which artery?
Anterior Interventricular A.
***Branch off Left Coronary A. Other 1/3 is from Posterior Interventricular A. off the Right Coronary A.
What are the branches of the Anterior Interventricular A. (branch off the LCA)?
Conus Branch
Lateral (Diagonal) A.
Interventricular Septal Branches
This branches off the Anterior Interventricular A. and supplies the Conus Arteriosus.
Conus Branch
This branches off the Anterior Interventricular A. and descends along the anterior surface of the heart.
Lateral (Diagonal) A.
This branches off the Anterior Interventricular A. and supplies the Interventricular Septum, Atrioventricular Bundle, and Right and Left Bundle Branches.
Interventricular Septal Branches
This branch off the Left Coronary A. travels posteriorly around the heart to the posterior aspect.
Circumflex A.
What are the branches of the Circumflex A. (off the Left Coronary A.)?
Left Marginal A.
Posterior Left Ventricular A.
This branch off the Circumflex A. travels along the left margin of the heart.
Left Marginal A.
