What is the correct sequence for flow of blood in the heart? o Superior vena cava → right ventricle → right atrium o Pulmonary vein → left atrium → bicuspid valve o Right atrium→ mitral valve → right ventricle o Inferior vena cava → left atrium → left ventricle o Right ventricle → aortic semilunar valve → aorta

What is the function of the heart? Explain.

Name the structure separating these two chambers of the heart. O anterior interventricular sulcus O chordae tendinae O interventricular septum O interatrial septum « Previous

As we auscultate the heart it is imperative, we understand what part of the heart we are listening to. Cellular senescence is observed when there is obstruction of the coronary circulation to the muscle tissue of the heart. If the left anterior descending artery (a.k.a. “Widow maker”) is occluded, predict an alternative route of blood flow to the myocardium. Start from the left coronary artery.

How would the left ventricle of a patient who had had high blood pressure for many years differ from the left ventricle of a normal heart?   A it would have a larger volume of muscle   B it would have a smaller volume of muscle   C it would be smaller than the right ventricle   D chronic high blood pressure would weaken the heart valves but would have no anatomical effects on the walls of the ventricles

Name the cord that connects that heart's apex with parietal peritoneum?

The Greek anatomist Erasistratus, originally from Ceos, identified the correct function of the right atrioventricular valve of the human heart, which was to prevent backward flow of blood from: the right ventricle to the right atrium the right ventricle to the left ventricle the right ventricle to the left atrium the left ventricle to the right ventricle

What are the four chambers of the heart called?

Compare and contrast the structure of the heart wall with that of arteries. Which three structures are homologous?

Outermost layer of the heart as organ itself     Composed of skeletal muscle     Composed mainly of cardiac muscle tissue     Also referred to as the epicardium     Area filled with serous fluid to decrease friction     Functions to bring air in and out of lungs     Outermost portion of sac composed of dense irregular connective tissue     Innermost layer of the heart organ     Middle layer of the heart organ     Most superficial layer secreting serous fluid     Entire protective structure surrounding heart     Identify location of entrance and exit of blood vessels     Tapered end of heart pointing toward left hip     Most deep layer secreting serous fluid     fills and empties of blood
