The semilunar valves of the heart open at the onset of the ejection period. Approximately what percentage of the stroke volume i
mr Goodwill [35]

The percentage of the stroke volume is ejected during the first quarter of systole will be approximately 60% to 65%

<u>Explanation:</u>

The time interval between the atria contraction and the relaxation of ventricles are called as a Cardiac cycle. Systole denotes the heart contraction during the blood pumping. Diastole refers to the heart relaxation when the blood is filled in the heart chambers. The total blood is not fully pumped by the ventricles.

Instead they will pump only a proportion of blood in each of the cardiac cycle.  The ejection fraction refers to the proportion of the intraventricular volume that is received as a output in circulation process. A human with normal heart functioning can have approximately 60-65%. This is known to be stroke volume. The blood volume that is ejected is strove volume.

Glucose -

Glucose is also not one of the answers because it is the END product of photosynthesis, not the thing that is needed for it to START.

Carbon Dioxide-

We, humans, breathe Oxygen, but plants breathe Carbon Dioxide and take out Oxygen, so that's why, Carbon Dioxide IS one of the answers.
