Session 9 Flashcards
What is the function of cardiac veins?
Return deoxygenated blood to pulmonary circulation.
Name the types of cardiac veins.
- Coronary Sinus
- Anterior Cardiac Veins
- Thebesian Veins
How many branches do the anterior cardiac veins consist of?
2-4 branches.
Where do the anterior cardiac veins enter?
Directly into the right atrium (RA).
What are Thebesian veins?
Microscopic vessels that drain directly into the RA.
What are the three main veins that access the coronary sinus?
- Great Cardiac Vein
- Middle Cardiac Vein
- Small Cardiac Vein
Which artery does the great cardiac vein run alongside?
Left anterior descending artery.
What does the great cardiac vein transition into?
Coronary sinus.
What prevents backflow at the junction of the great cardiac vein and coronary sinus?
Valve of Vieussens.
What does the oblique vein of Marshall drain?
Left atrium (LA).
Which artery does the middle cardiac vein run alongside?
Posterior descending artery.
What does the middle cardiac vein drain?
- Right ventricle (RV)
- Left ventricle (LV)
- Interventricular septum
Which artery does the small cardiac vein run alongside?
Acute marginal artery.
What does the small cardiac vein drain?
- Right ventricle (RV)
- Left ventricle (LV)
- Both atria
- Anterior portion of the interventricular septum
Name the three veins that drain into the coronary sinus.
- Great cardiac vein
- Middle cardiac vein
- Small cardiac vein
What chamber does the oblique vein of Marshall drain?
Left atrium.
