How is the heart rate modified according to the needs of the body?
When you are working hard, it will beat faster to get oxygen to the body more quickly. When resting, it will beat more slowly.
Why does heart beat increase during exercise?
Because the heart has to pump more oxygen than usual to your muscles
Why will your heart beat faster after you run?
- Muscles require oxygen to function - When running, you are working muscles - Blood carries oxygen, the heart pumps blood When running, as the muscles require more oxygen to work harder, the heart must pump blood around your body quicker, delivering more oxygen to the muscles that require it. The way that the heart does this is to increase heart rate.
Why do you think the speed of the heart changes?
When you exert, the cells need more oxygen. The heart delivers blood that carries oxygen, so as the demand for oxygen increases the heart rate (and the volume of blood delivered on each beat) increases.
