Answer:
The normal ejection fraction of heart is 55% to 75%
Step-by-step explanation:
Ejection fraction may be defined as the amount of blood pumped in the left and right ventricle during the normal heart beat. The main pumping chamber of heart is left ventricle.
55% to 75% is the normal ejection fraction of the heart. The normal ejection fraction of heart refers the normal pumping ability of heart. The ejection fraction range below or above the normal may indicate the improper functioning of heart.
