If the Mitral Valve failed in a patient, would the blood flow back into the Right Ventricle? Question 6 options: Only if the pulmonary semilunar valves also fail Only if the aortic semilunar valves also fail No, because the flow would be stopped by the bicuspid valve No, because blood can only flow forward, never in the reverse direction.

Which of the following statements is CORRECT concerning the mitral valve? Question 12 options: Pectinate muscles help open this valve by pulling down on the chordae tendineae This valve closes when pressure in the left ventricle exceeds that of the left atrium The papillary muscles open this valve by pushing on the chordae tendineae This valve opens when pressure in the right atrium exceeds that of the right ventricle
QUESTION 8 Which sequence is correct regarding the direction of blood filow through the cardiovascular system: O Aorta, pulmonary artery, vena cava, pulmonary vein O Aorta, carotid artery, pulmonary vein, pulmonary artery O Pulmonary vein, pulmonary artery, aorta, Vena cava O Aorta, pulmonary vein, tricuspid valve, left ventricle O Aorta, Vena cava, tricuspid valve, right ventricle
Which of the following occurs during diastole? Question 25 options: The semi-lunar valves are open but the AV valves are closed. Blood is forcefully pumped out of the ventricles and into the aorta and pulmonary arteries. Blood flows into the ventricles. Cardiac muscles contract.
QUESTION 3 The atrioventricular valves are open when ventricular, arterial arterial, ventricular ventricular, atrial atrial, ventricular QUESTION 4 The semilunar (V-a) valves are closed when atrial, ventricular ventricular, atrial ventricular, arterial O arterial, ventricular pressure > pressure > pressure. pressure
QUESTION 6 Which sequence is correct regarding the direction of blood flow through the cardiovascular system: Pulmonary vein, left atrium, left atrium, pulmonary artery Pulmonary vein, left atrium, left ventricle, aorta Pulmonary artery, aorta, left atrium, right atrium Vena cava, right atrium, aorta, right ventricle Vena cava, right atrium, pulmonary vein, right ventricle
Which of the following contains blood with a relatively high oxygen content? Group of answer choices left ventricle right atrium right ventricle left atrium
The left ventricle: Question 21 options: Has thinner muscular walls than does the right ventricle Receives blood from the left atrium through the tricuspid valve Pumps blood out of the heart into the pulmonary circuit Sends blood out through the aortic semilunar valve to the systemic circulation ALL of these are correct
Put the structures involved in blood flow through the heart in order, as blood flows from the body back to the heart, and then from the heart to the body. Question 5 options: right A-V valve pulmonary trunk mitral valve pulmonary veins
Which event occurs during ventricular systole? Question 43 options: Chordae tendineae are loose Semilunar valves are closed The left ventricle is dilated Papillary muscles are relaxed Atrioventricular valves are closed
Question 33 Which of the following is the THICKEST? ORight ventricle endocardium Right atrial epicardium Right atrial myocardium Left ventricular endocardium
The first heart sound (the LUB of the lub-dup you hear through a stethoscope) is due to which 2 of the following? Pick 2 answers: closing of the tricuspid valve closing of the pulmonary valve closing of the bicuspid valve O closing of the aortic valve
If the left side of the heart fails, then __________________________ Group of answer choices 1)the heart is unable to move blood from the pulmonary circuit to the systemic circuit at the rate needed. This would result in the back up of blood in the lower legs with resulting edema 2)the heart is unable to move blood from the systemic circuit to the pulmonary circuit at the rate needed. This would result in the back up of blood in the aorta. 3)blood would not back up at all, but rather pressure would increase in the left ventricle. 4)the heart is unable to move blood from the pulmonary circuit to the systemic circuit at the rate needed. This would result in the back up of blood in the pulmonary circuit.
