Question
Which of the following are true regarding the heart?
The mitral valve opens during diastole to allow blood to flow from the right atrium to the right ventricle
The tricuspid valve is a semi-lunar valve anchored to the heart by the myocardium
The aortic valve opens during ventricular systole
Atrial pressure increases during ventricular systole
Ventricular pressure increases during atrial and ventricular systole
P waves are associated with preloading the ventricles
correct
-A.B.The mitral valve opens during diastole to allow blood to flow from the right atrium to the right ventricle
-A.B.The tricuspid valve is a semi-lunar valve anchored to the heart by the myocardium
-A.B.The aortic valve opens during ventricular systole
-A.B.Atrial pressure increases during ventricular systole
-A.B.Ventricular pressure increases during atrial and ventricular systole
-A.B.P waves are associated with preloading the ventricles
A.correct
B.Explanation / Answer
Mitral valve open durinfg ventricluar systole abd prevent backward flow of blood from ventricle to atria.
Semilunar valve -aortica nd pulmonary valve not tricuspid.
When ventricular pressure exceed aortic pressure durin syatole aortic valve opens . So it is corect...onset of ventricular systole causes buldging of v valve intovthe atrium causing sudden sharp rise in pressure .it is correct.
Ventricular pressure increse during ventricular syatole.
