How much blood is pumped out of the left ventricle every contraction?

During each contraction, the left ventricle pumps approximately 70 milliliters of blood, a volume known as stroke volume. This amount can vary based on factors such as an individual’s size, fitness level, and overall health. In a healthy adult, the heart beats around 60 to 100 times per minute, leading to a significant amount of blood circulated throughout the body each minute.
