What causes heart rate to accelerate?
The heart beats accelerates because your organs need more oxygen and the heart pumps the oxygen into the blood and when you need more oxygen than normal your heart rate is faster than normal.
Why does the heart beat faster when exerciseing?
As you exercise, the muscles need more oxygen to work. The heart beats faster to get the oxygenated blood from the lungs to the muscles. The harder you exercise, the more oxygen the muscles need, the faster the heart beats.
Why does a mammal need more oxygen than a reptile of the same size?
Yes, mammals have a 4chambered heart, while reptiles only have a 3chambered heart.
Why does heart rate and respiration go up with exercise?
The more you exercise - the more oxygen your body's muscles need. In order for your heart to supply more oxygen - it must beat faster.
When you do exercise do your bodies need more or less oxygen?
your body needs more oxygen to keep the heart going at a more steady pace.
Why does you heart sometimes need to work harder?
Your heart may need to work harder when your body requires more oxygen. For instance, if you are exercising, your heart rate increases to keep up with the muscles' oxygen requirements.
Why does heart rate increases?
because you need more oxygen to be delivered to the muscle and more waste to the lungs. when you are exercising your muscles need oxygen so the blood stars pumping faster to get the oxygen to the 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.
What is the relationship between heart rate and breathing rate during physical activity?
During physical activity, the heart rate and breathing rate increase to supply more oxygen to the muscles. This is because the heart needs to pump more blood to deliver oxygen, and the lungs need to take in more air to provide oxygen to the blood.
How does exercise effect heart rate?
== == it helps because it exercises your heart so it doesn't have to pump so much blood when you are exercise.
Why does your body need more oxygen when you work out?
Because you are making the heart work faster,so it has to pump more blood around it.
