Why are the integration bounds from -pi/2 to pi/2 and not 0 to pi?

Because the angle is with respect to the positive y-axis.Why are the integration bounds from -pi/2 to pi/2 and not 0 to pi?
Look at the diagram. Note where the angle θ is. If θ was 2π, where would that put the radius vector?what's the proof? I can't understand why this is the case
Thank you
