11).THE \"a\" WAVE IN THE JUGULAR VENOUS PULSE

b) is due to atrial contraction
c) occurs immediately before the p wave on the ECG
d) is caused by atrial filling during ventricular systole
e) increases in amplitude on inspiration

Answers- The sequence of waves in JVP is
a wave is -atrial systole which occurs after the electrical event of atrium- P wave.Atrial systole is just before ventricular systole.
c- ventricular systole
x descent d/t L ventricular movement down and left during early systole.
v- venous filling of ventricle during diastole
y descent d/t TV opening.
