• C) Tricuspid and pulmonic valves

• D) Mitral and aortic valves

The 'Dub' (S2) sound is best heard at the ________.

• base

• apex

• left sternal border

• mitral area

What is the correct order of the electrical conduction pathway in the heart?

• AV node → SA node → bundle of His → bundle branches → Purkinje fibers

• SA node → AV node → bundle of His → bundle branches → Purkinje fibers

• Bundle of His → SA node → AV node → Purkinje fibers

• AV node → bundle branches → SA node → Purkinje fibers

The SA node is known as the ________ of the heart.

The direction of blood flow through the heart starting from when deoxygenated blood returns to the heart is:

• Right atrium → Right ventricle → Pulmonary artery → Lungs → Left atrium → Left ventricle → Aorta

• Left atrium → Left ventricle → Pulmonary artery → Lungs → Right atrium → Right ventricle → Aorta

• Right ventricle → Right atrium → Pulmonary vein → Lungs → Left ventricle → Left atrium → Aorta

• Right atrium → Left atrium → Right ventricle → Left ventricle → Aorta → Lungs
