How does the heart pump work to circulate blood throughout the body?
The heart pumps blood by contracting and relaxing in a rhythmic manner. When the heart contracts (squeezes), it pushes blood out into the arteries. This blood then travels through the body, delivering oxygen and nutrients to cells and removing waste products. When the heart relaxes, it fills up with blood from the veins, ready to pump again. This continuous cycle of contraction and relaxation helps circulate blood throughout the body.
