Explain how heart impels the blood?
Expert
The heart is a muscular organ which comprises chambers (that is, right atrium and right ventricle and left atrium and right ventricle) via which blood passes. The blood enters the heart in atria, goes to the ventricles and then departs the organ.
Blood is pumped out of the heart by the contraction of muscle fibers which form the ventricular walls. The contraction decreases the ventricle volume therefore raising the internal pressure and the blood then flows to exit the vessels (pulmonary artery for right ventricle and aorta for left ventricle). Whenever ventricular muscle fibers distend the ventricles recover their original size and obtain new blood flow coming from atria.
