Question

Match the letters on the graphs with the descriptions below. Use the liters on the EKG for electrical descriptions and the letters on the ventricular volume graph for all other descriptions. Use multiple letters if it is appropriate. all valves are closed _b__ atrial depolarization _b__AV valves are open _h__ ventricular systole begins _c__ ventricular repolarization _b__atrial contraction occurs here -h-loft ventricular pressure is greater than atrial pressure but less than aortic pressure _ h|__ region where end systolic volume is described _h_ region where semilunar values are open _region where greatest pressure is reached in the left ventricle __ if the heart rate slowed, the value in this region would increase before ventricular contraction _b__ region where atrial pressure is greater than ventricular pressure

Explanation / Answer

Dear student, as per Chegg rules I can only answer 4 of the sub-parts.
Now although understanding this picture is a bit unclear, I am going to answer the blank subparts hoping that is what you are expecting.

1. "a" is the region where all valves are closed.

If you look at the cardiac cycle, "a" is the area of isovolumetric relaxation, and that is when ventricles relax, leading to the closing of all valves of the heart.

2. Region where greatest pressure is reached in left ventricle- is Ventricular ejection.
This would roughly correspond to the area of "d" and later part of "h" .

3. "e"

In the event of slow heart rate, the value of 'what' increases is not given. I am assuming it is the ventricular volume, since that will be the most probable event. Hence, region 'e' will increase.

Hope this helps. All the best!
