Question

Quizplus · Accepted Answer

The v wave is caused by filling of the atrium from peripheral veins during early diastole.

Answer: C 
 The c wave is caused by contraction of the atrium during systole.

Answer: A 
 The a wave is caused by contraction of the atrium during late diastole.

Answer: E 
 The y descent is the rapid decline in right atrial pressure following the opening of the tricuspid valve and the emptying of blood from the atrium to the right ventricle.

Answer: D 
 The x descent is the rapid decline in right atrial pressure during ventricular systole caused by the downward movement of the atrioventricular ring.
