Right coronary artery

This video tutorial focuses on the right coronary artery, a key component of coronary circulation that nourishes the heart. It details the artery's pathway, the areas it supplies, and its branches, including the sinoatrial nodal branch, right marginal branch, and atrioventricular nodal branch. The tutorial concludes with a call to explore more resources on Kenhub for interactive learning.
