Q. Doctors use stethoscope to hear the sounds produced during each cardiac cycle. The first sound is heard when:

1. Ventricular walls vibrate due to pushing in of blood from atria
2. Semilunar valves are closed
3. AV node receives signal from SA node
4. The tricuspid and bicuspid valves are closed

Q.

Identify the valves of the heart by Position :

1. 1.Pulmonary valve 2.Tricuspid valve 3.Mitral valve 4.Aortic valve

2. 1.Mitral valve 2.Aortic valve 3.Tricuspid valve 4.Pulmonary valve

3. 1.Aortic valve 2.Tricuspid valve 3.Pulmonary valve 4.Mitral valve

4. 1.Tricuspid valve 2.Pulmonary valve 3.Mitral valve 4.Aortic valve

Q. The second heart sound (dub) is associated with the closure of:

1. Tricuspid valves
2. Semilunar valves
3. Bicuspid valves
4. Tricuspid and bicuspid valves

Q.

Assertion[A]: Atria and ventricles do not contract at the same time.

Reason[R]: This time delay allows proper filling of all the 4 chambers of the heart and results in an efficient pumping of blood.

1. A is true and R is false.

2. R is true and A is false.

3. Both A and R are true and R is correct explanation of A.

4. Both A and r are true but R is not correct explanation for A.

Q. Mitral valve prevents the backflow of blood from ____________ to _____________.

1. right atrium, right ventricle
2. left atrium, left ventricle
3. aorta, left ventricle
4. left ventricle, left atrium

Q. Label the highlighted regions in the following diagram:

1. Tricuspid valve
2. Aortic valve
3. Pulmonary valve
4. Mitral valve
