Answer to Question 1

D
A standard 12-lead ECG provides views of the heart in both the frontal and horizontal planes and views the surfaces of the left ventricle from 12 different angles.

Answer to Question 2

A
When the ventricles contract, the semilunar valves open, allowing blood to flow out of the ventricles. When the right ventricle contracts, blood that is low in oxygen flows through the pulmonic valve into the right and left pulmonary arteries. When the left ventricle contracts, freshly oxygenated blood flows through the aortic valve into the aorta and out to the body.
