Blood Supply
The blood supply can vary.
- The blood supply of the AV node is from the posterior interventricular artery, which is a branch of the right coronary artery in right-dominant individuals.
- In the remainder of individuals, the AV node is still supplied by the posterior interventricular artery, but that artery is a branch of the left circumflex artery; the coronary circulation of these individuals is considered left-dominant.

Famous quotes containing the words blood and/or supply:
“See, see where Christ’s blood streams in the firmament!
One drop would save my soul—half a drop! ah, my Christ!—
Ah, rend not my heart for naming of my Christ!—
Yet will I call on him!—O, spare me, Lucifer!—
Where is it now? ‘T is gone; and see where God
Stretcheth out his arm, and bends his ireful brows!—
Mountains and hills, come, come and fall on me,
And hide me from the heavy wrath of God!”
—Christopher Marlowe (1564–1593)
“Odors from decaying food wafting through the air when the door is opened, colorful mold growing between a wet gym uniform and the damp carpet underneath, and the complete supply of bath towels scattered throughout the bedroom can become wonderful opportunities to help your teenager learn once again that the art of living in a community requires compromise, negotiation, and consensus.”
—Barbara Coloroso (20th century)
