Answer 1

3. Diaphragm is present below the lungs and heart. It is a muscular dome shaped structure which helps in respiration. Answer is b.

4. Injection of dye into the vascular system is semi-invasive or minimally invasive procedure. Answer is a.

5. The four valves of the heart are tricuspid , mitral, pulmonary and aortic. Triscuspid valve (right) and mitral valve (left) control flow of blood from atria to ventricles. Pulmonary valve controls blood flow from right ventricle to lungs and aortic valve from left ventricle to body organs. Answer is a.

6. Median sternotomy is the vertical incision along the center of the sternum. Answer is b.

7. OPCAB is off-pump coronary artery bypass. Answer is b.

8. A history of strep throat or infection by Streptococcus or frequent tonsillitis as a child can lead to damage of cardiac valves.
