Which of the following statements regarding the heart valves is false?
Which of the following statements regarding the heart valves is false? a. Astenotic valve forces the heart to "repump" the same blood over and over again because the blood "leaks" backward.
b. Scar tissue formation or congenital defect may cause valve stenosis (narrowing).
c. Regurgitation murmur is another term for an incompetence murmur.
d. Rheumatic fever tends to damage/destroy heart valves, thus creating murmurs.
e. An insufficiency murmur results when a heart valve fails to close completely
Final answer:The false statement regarding heart valves is the one that describes a stenotic valve as allowing blood to 'leak' backward. Stenosis involves a narrowing of the valve and not a backflow, which is actually characteristic of valve regurgitation or insufficiency.Explanation:The statement from the student's question that is false is: a. A stenotic valve forces the heart to 'repump' the same blood over and over again because the blood 'leaks' backward. This statement incorrectly describes a stenotic valve which actually refers to a valve that has become narrowed or obstructed, making it difficult for blood to flow through it. This condition forces the heart to work harder to pump blood through the narrowed valve, but it does not involve blood leaking backward. Instead, blood leakage typically occurs in cases of valve regurgitation or valve insufficiency, when a valve does not close completely.Conditions such asvalve prolapsecan lead to regurgitation which is the backflow of blood, creating a murmur that can be detected by auscultation using a stethoscope. Valvular defects may arise due to congenital malformations, infections, or other cardiovascular issues and can lead to stenosis or insufficiency, both of which can have serious implications on heart function and efficiency....
