<prompt> Pelo e pompa mali joang meleng?nan  <response>: Instruction in English: How does a heart pump blood to the body? . Response in English: The heart is a muscular organ that pumps blood to the body by contracting and relaxing in a rhythmic way. It has four chambers: two upper chambers called the atria and two lower chambers called the ventricles.Here is how the process works:1. Oxygen-poor blood from the body returns to the right atrium of the heart through the inferior and superior vena cava, two large veins2. The right atrium contracts and pushes blood through the tricuspid valve into the right ventricle.3. The right ventricle contracts and sends blood through the pulmonary valve into the pulmonary artery, which carries it to the lungs. In the lungs, the blood picks up oxygen and releases carbon dioxide.4. Oxygen-rich blood from the lungs flows into the left atrium via the pulmonary vein.5. The left atrium contracts, and the blood is pushed through the mitral valve into the left ventricle.6. The left ventricle contracts and sends the oxygen-rich blood through the aortic valve into the aorta, the largest artery in the body.7. The aorta and its branches carry the oxygen-rich blood to all the tissues in the body, providing them with the oxygen and nutrients they need.As the heart contracts and relaxes, it creates a pulse that can be felt in various locations, such as the wrist or neck. The whole process is regulated by electrical impulses generated by the hearts own pacemaker, the sinoatrial SA node, and conducted through the heart muscle by a specialized conduction system. .
