breathing is controlled by the level of co2 in the blood, (not due to the fact that there may be low amounts of o2), there are chemoreceptors that measure the pH level of the blood, remember that co2 can be transported in the blood as carbonic acid, thus this acid lowers the pH. if a low pH is detected, it sends nerve impulses to our brain, that stimulates us to breathe in an effort to get rid of the co2.
CO2
we breathe out a gas called carbon dioxide
Oxygen
We need to breathe oxygen to live.He kept telling me to breathe easy. I'd like to see him breathing easy while giving birth.The oxygen tanks allow us to breathe underwater for a while.
Plants and us Plants are our food, they improve our air and they are used to make many things that we need such as medicines, clothes and paper. Trees are cut down and the timber used to build houses and furniture. Plants are useful to us in many ways. We need oxygen in the air we breathe. Plants take in the carbon dioxide gas that we breathe out and turn it into oxygen. Plants keep the air we breathe stocked full of oxygen. Plants are food for us. They give the us the vitamins and minerals we need to grow and stay healthy. =) ~
Blood releases its oxygen into the tissues at the capillary level.
NO
no it is hazardous for us to breath in such an environment
No, Carbon Dioxide is the gas that plants use in Photosynthesis to transform it into oxygen for us to breathe.
when you breathe out,the gas that is emitted is
There are many reasons why gases are important to us. For example, the air that we breathe is a gas.
we breathe out a gas called carbon dioxide
Oxygen. You breathe out CO2
