Final answer:
The amount of blood ejected from the left ventricle during each beat is called the stroke volume. It is typically in the range of 70-80 mL. The left ventricle pumps the same amount of blood as the right ventricle, although the pressure generated by the left ventricle is higher.
Step-by-step explanation:
The amount of blood ejected from the left ventricle during each beat is called the stroke volume. Stroke volume refers to the quantity of blood that is pumped out of the left ventricle with each contraction. It is typically in the range of 70-80 mL.
Stroke volume is an important measure in cardiac physiology and is used to calculate other parameters such as ejection fraction. Ejection fraction is the percentage of blood pumped or ejected from the heart with each contraction and is calculated by dividing stroke volume by the end-diastolic volume (EDV).
The left ventricle, despite having higher pressure than the right ventricle, pumps the same amount of blood. This is because the pressure in the aorta is much higher, thus requiring greater force to pump blood throughout the body.
