Answer 1

Wiggers diagram:

1. A Wiggers diagram is a regular illustration adapted in teaching physiology of cardiac studies.
2. The X-axis in the Wiggers diagram is used to plot time, while Y-axis depicts these factors on a single grid:
   1. Blood pressure
   2. Heart sounds
   3. Ventricular volume
   4. Arterial flow
   5. Electrocardiogram
3. The Wiggers diagram demonstrates a coordinated variation of these values with heartbeat, thus helping one in an understanding of the complete cardiac cycle.
