When you know the heart pumping method is circulatory system, which issue do you remember particularly? What’s the reason for that? |

Answer» The heart beats faster during and after an exercise remembered by me. Because at that time our body needs more energy under these conditions. The faster breathing of heart pumps blood more rapidly to the body organs which supplies more oxygen to the body cells for rapid respiration to produce more energy. That is a great job for heart muscle. |
