The closure of which valve is assisted by the diaphragm?
The Ileocecal valve
What is the Improper closure of valve between atrium and ventricle during systole?
mitral valve prolapse
What cardiac cycle corresponds to the dicrotic notch?
aortic valve closure
What parts of the heart make the beating sound?
The first heart sound, the so called "lub", comes from the closure of the atrioventricular valve. The second heart sound, the "dup", comes from the closure of the semilunar valve.
What might be the significance of nonfuctional or defective chordae tendinae?
Failure of valve closure
What is 'water hammer' as referred to in flow through pipes?
sudden stopages of flow by the closure of a valve
Would turbulence of blood flow through the aortic valve give rise to the first heart sound?
No. The heart sounds are caused by the closure of heart valves. The first heart sound is caused by the closure of the AV valves (tricuspid and mitral). The second heart sound is the result of the closure of the aortic and pulmonic valve after the completion of systole. Turbulence of blood flow through the aortic valve would cause a murmur (an abnormal heart sound) during systole.
Why the splitting of 1st heart sound is not heared?
S1 is normally slightly split (~0.04 sec) because mitral valve closure precedes tricuspid valve closure; however, this very short time interval cannot normally be heard with a stethoscope so only a single sound is perceived.
What is an abnormal prolonged heart sound caused by incomplete closure of heart valves?
Abnormal heart sound caused by improper closure of heart valve is called a murmur. A murmur is caused by turbulent blood flow, when a heart valve either fails to open normally or fails to fully close.
Which action leads to the closure of the right AV valve?
A person will not be able to say which valve would close someone needs to know what the valves are closed. This information is needed to answer the question.
What event results in the pressure deflection called the dicrotic notch?
When the aortic semilunar valve snaps shut, a momentary increase in the aortic pressure results from the elastic recoil of the aorta after valve closure.
The beating sound your heart makes comes from?
From the closure of the two flaps of the mitral valve in the left ventricle
