QuestionChoice
The right marginal artery arises from the right coronary artery. The right marginal artery travels along the right and inferior border of the heart, supplying both the right ventricle and the apex.

Right ventricle and apex
QuestionChoice
The left coronary artery first branches to give the left anterior descending artery. It then continues and gives rise to the left circumflex and left marginal artery. The circumflex artery supplies the left atrium and the left ventricle. The left ventricle also receives blood from the left coronary, left anterior descending and left marginal arteries (and from the posterior interventricular artery, which arises from the right coronary artery in the majority of people). The anterior ventricular septum is supplied by the left anterior descending artery.

Anterior ventricular septum
QuestionChoice
The right coronary artery is marked here and is a major branch of the hearts blood supply. It supplies both right atrium and ventricle. The left atrium is supplied by branches from the left coronary artery, namely the left anterior descending artery and circumflex artery.

e
Lateral left ventricle
QuestionChoice
The right coronary artery is marked here. The right coronary artery supplies the right side of the heart, including the right atrium and ventricle. The right ventricle also receives blood from the right marginal artery. The right coronary artery also supplies the sinoatrial node (via the sinoatrial nodal artery) and atrioventricular node (via the atrioventricular nodal artery) in the majority of people (60% and 85% respectively).
