Question

The apex is the superior part of the heart and the base is the inferior part. The apex of the heart rests on the diaphragm. (True) or (false) Deoxygenated blood is high in carbon dioxide and low in oxygen. Oxygenated blood is high in oxygen and low in carbon dioxide. Which branches of the left coronary artery lie in the anterior interventricular sulcus? Circumflex artery Left marginal artery. Right anterior interventricular artery Left anterior interventricular artery. The pulmonary trunk is the major artery leaving the right ventricle. Like all arteries, it carries deoxygenated blood. (True) or (False) The aorta and pulmonary trunk are elastic (conducting) arteries. Which wall layers of the aorta and pulmonary trunk contain an abundance of elastic tissue allowing them to withstand the pressure as blood is ejected from the ventricles? Tunica media Tunica intima Tunica externa The superior and inferior vena cava return deoxygenated blood from the body to the right atrium. (True) or (false) The fossa ovalis is the remnant of the foramen ovale in the fetal heart. (True) or (false) The coronary sinus is located on the posterior of the heart. (True) or (false) The coronary veins return deoxygenated blood from the cardiac veins to the right atrium. The function of valves is to prevent backflow. Which valve is located between the right atrium and the right ventricle? Tricuspid valve Bicuspid valve Pulmonary semilunar valve What type of valve is located between the left ventricle and the aorta? Semilunar Atrioventricular When comparing the thickness of the heart wall between the right and left ventricles, the left ventricle has the thicker wall.
