Question

Which blood vessel lies in the anterior interventricular sulcus and supplies oxygenated blood to both ventricles?

1) Aorta
2) Pulmonary artery
3) Coronary artery
4) Superior vena cava

Answer 1

The left anterior descending artery (LAD), a branch of the left coronary artery, is the vessel in the anterior interventricular sulcus that supplies oxygenated blood to both ventricles, making the Coronary artery the correct answer.

Step-by-step explanation:

The blood vessel that lies in the anterior interventricular sulcus and supplies oxygenated blood to both ventricles is the left anterior descending artery (LAD), which is a major branch of the left coronary artery. As it travels down the anterior interventricular sulcus, the LAD distributes blood to both the left and right ventricles of the heart. It gives rise to numerous smaller branches that interconnect with the branches of the posterior interventricular artery, forming anastomoses, which are connections between blood vessels that allow circulation to continue even if there is a blockage in another area. Thus, the correct answer to the question is option 3) Coronary artery.
