उत्तर
In human beings the oxygen rich blood is pumped out to the body by contraction of left ventricle.
Explanation:
In the circulatory system of a normal human being, the oxygenated blood is pumped to all parts of the body during the contraction of the left ventricle. This phase is known as systole. The left ventricle pumps oxygenated blood into the aorta, which then distributes it to the rest of the body.
