The coronary circulation is responsible for nourishing the heart during its tireless effort in pumping blood around the body. In this video, we focus on the right coronary artery.
Along with the left coronary artery, the right coronary artery branches off of the ascending aorta. The right coronary artery passes through the atrioventricular groove to the right side and continues on to the posterior surface of the heart. It supplies the right atrium, the majority of the right ventricle, the left ventricle portion that communicates with the diaphragm (areas of the interarterial and interventricular septa), the sinoatrial node in about 60% of the population, and the atrioventricular node in general.

0.65 -> Hey there everyone!
1.65 -> It’s Matt from Kenhub, and in this tutorial,
we will be discussing the right coronary artery.
11.74 -> The coronary circulation is responsible for
nourishing the heart during its tireless effort
17.289 -> in pumping blood around the body.
19.57 -> The focus of this video is the right coronary
artery, which you can find here highlighted
24.08 -> in green on this image of the anterior view
of the heart.
28.21 -> Along with the left coronary artery, the right
coronary artery branches off of the ascending
33.73 -> aorta.
37.23 -> The right coronary artery passes through the
atrioventricular groove to the right side
43.04 -> and continues on to the posterior surface
of the heart.
47.11 -> It supplies the right atrium, the majority
of the right ventricle, the portion of the
54.89 -> left ventricle that communicates with the
diaphragm (areas of the interatrial and interventricular
61.76 -> septa), the sinoatrial node in around sixty
percent of the population, and the atrioventricular
69.44 -> node in general.
74.31 -> This artery further divides into several branches
including the sinoatrial nodal branch, the
80.561 -> right marginal branch which runs to the right
margin of the heart, and the atrioventricular
86.2 -> nodal branch which supplies the atrioventricular
node at the junction of the four heart chambers
92.72 -> within the septae on the posterior side of
the heart.
96.79 -> Lastly, a posterior interventricular branch
runs along the posterior interventricular
104.36 -> groove.
106.81 -> This video is more fun than reading a textbook,
right?
