oxygen
because more oxygen is needed.
Your rate of breathing increases in a crowded area because there is less oxygen. This is because there are more people breathing in the oxygen.
Two ways to increase oxygen pick up by mammals would include breathing more deeply and breathing more rapidly
Breathing.
When we take exercise our body needs more oxygen .Our normal breathing rate do not fulfill the oxygen requirement due to which breathing rate is increased.
increase in humidity can only happen if the location is currounded by water like coastal regions or in case of heavy rainfalls ..if it rains regurlarly like in the amazon rain forests. No it doesn't affect breathing..you will sweat more ..if humidity increases. breathing is affected by reduced oxygen content or reduced atmospheric pressure.
Because the local rise in carbon dioxide levels triggers a feedback system that increases breathing to increase the blood oxygen level. There is probably some anxiety effect in some people too.
At high altitude, there is less oxygen, so breathing rate is increased to compensate.
To increase the oxygen intake to stimulate the heart and lungs. You can try exercises like pursed-lip breathing and deep belly breathing to open your airways and increase the amount of oxygen in your body.
No - we exhale to remove air that has a high content of carbon dioxide. Excess oxygen is not a problem when breathing - oxygen deficiency IS a problem.
No, but there is less oxygen. This makes breathing harder.
There is an increase in the breathing rate, this is due to the demand for oxygen from the working muscles. •The Respiratory Volume increases, this is due to the increase of Tidal Volume and breathing rate whilst meeting the demand of oxygen for the working muscles.
