Which of the following vessels lie in the coronary sulcus? The marginal artery and circumflex artery The anterior and posterior interventricular arteries The right and left semilunar arteries The superior and inferior venae cavae The great and middle cardiac veins

Question 13 Which of the following does NOT empty into the right atrium? The right and left pulmonary veins, the Inferior vena cava, the superior vena cava, the coronary sinus. Question 14 Which of the following is NOT true of the coronary circulation? The left coronary artery branches into the anterior interventricular artery and the circumflex artery. The coronary arteries deliver blood to the heart tissue during ventricular diastole. The left ventricle receives most of the blood supply.

Sulcus, running alongside the anterior interventricular artery. At the coronary sulcus, it travels with the circumflex artery to the posterior surface, where it drains into the coronary sinus. Find the small cardiac vein as it travels alongside the right marginal artery toward the coronary sulcus. Along the coronary sulcus, it travels with the right coronary artery to the posterior surface and drains into the coronary sinus. The anterior cardiac veins are small veins that travel a short distance along the anterior surface of the right ventricle. They drain directly into the right atrium. Anterior view On the posterior surface of the heart, identify two other veins that drain into the coronary sinus: Coronary sinus The posterior cardiac vein travels with the left marginal artery along the left ventricular wall. The middle cardiac vein ascends along the posterior interventricular sulcus, traveling with the posterior interventricular artery. Posterior view MAKING CONNECTIONS By observing the paths of the coronary arteries and their branches, predict the regions of the heart wall that will be supplied by the following blood vessels: Anterior interventricular artery Circumflex artery Posterior interventricular artery Right marginal artery Left marginal artery
