3. In chest X-Ray PA view, right border of cardiac shadow is formed by which structure? L a. Left atrium. b. Left ventricle. c. Right atrium. d. Right ventricle. e. Pulmonary trunk.

The period of ejection: A. begins with closure of the AV-valves and ends with opening of the AV- valves B. begins with opening of the aortic valve and ends with closure of the aortic valve C. begins with the P-wave and ends with the QRS-complex D. begins with the QRS-complex and ends with the T-wave
