Final answer:
The right marginal artery supplies the right border of the heart, the posterior interventricular artery supplies the posterior surface of both ventricles, and the left coronary artery (including the LAD and circumflex branches) supplies the left atrium and left ventricle.
Step-by-step explanation:
The task is to match the specific area of the heart on the left side with the branch of the right coronary artery that supplies it. Based on the provided information, we can determine:
- The right border of the heart is mainly supplied by the right coronary artery and its marginal branches.
- The posterior surface of both ventricles is primarily supplied by the posterior interventricular artery, which is a branch of the right coronary artery.
- The anterior surface of both ventricles is supplied by the left coronary artery, specifically the anterior interventricular artery, also known as the left anterior descending (LAD) artery.
- The left atrium and ventricle are mainly supplied by the left coronary artery, especially through its circumflex branch.
Therefore, the matches would be as follows:
- The right border of the heart — Not directly mentioned here, but it is generally supported by the right coronary artery.
- Posterior surface of both ventricles — Posterior interventricular artery.
- Anterior surface of both ventricles — Does not match with the right coronary artery as it is supplied by the left coronary artery (LAD).
- Left atrium and ventricle — Does not match with the right coronary artery as it is supplied by the left coronary artery (circumflex branch).
