Drink more Water!
An increase in oxygen level can be caused by processes such as photosynthesis in plants, diffusion of oxygen into water from the atmosphere, or release of oxygen during chemical reactions. Human activities may also contribute to an increase in oxygen levels by reducing pollution or planting trees that produce oxygen.
don't smoke, excercise, espessially walking.
Low level of carbon- dioxide and more level of oxygen.
because the level of oxygen in the air is so low, the body would need to breath more often to be able to absorb the same amount of oxygen it would at a lower altitude. So, breathing rate would increase. also the heart rate would increase.
We breathe faster when we exercise to increase the amount of oxygen available to our bodies.
The fertilizer causes an increase in algae. As algae die and are decomposed the decomposers increase and use up all of the oxygen in the water.
it mainly depends on the persons fitness level. a fit person is more efficient at using the oxygen so their heart needs to pump the blood through their body less often.
If your heart rate increases AFTER running, there is something wrong and you need to see your doctor. Heart rate increases WHILE you are running, and should start to come down after the running stops.
The level of oxygen that the body is getting is low so it would most likely start to breath faster. By doing that the heart rate will also increase so that the blood can deliver the oxygen to the tissues. Over all the body will produce more red blood cells to use the oxgen efficiently.
The aorta just as it comes out of your left ventricle.
Cardiac output will level off as your heart muscle strengthens and your body becomes accustomed to physical activity. For example, when first getting started, walking 5 minutes may be enough to increase your heart rate, but within a few weeks, you will need to increase the intensity of your walk to increase your heart rate by the same amount.
