there are many species that have no hearts at all , such as coral, sea cucumbers , flatworms and nematodes . animals that survive without heart do not rely on blood being pumped to their internal organs in order to function .

Replying to

1 . because of the valves , the blood can only move in one direction as it gets squeezed along , so its a combination of blood pressure from heart pumping action , the valves and muscle movement that gets blood up the legs against gravity .

2. its an arrhythmia or a problem how your heart beats

3. the chest pain is caused by , poor blood flow to heart . which basically cause chest pain which causes (heart attacks )
