While breathing only oxygen is absorbed, because hemaglobin in red blood cells selectively absorbs oxygen and not other gases.
No, They have two. There are no animals except some kinds of snakes that have only one lung.
Approximately 16% to 17% of inhaled oxygen is exhaled during normal breathing. The exhaled air still contains a significant amount of oxygen, as our bodies only use a small portion of the oxygen we breathe in for cellular respiration.
Frogs have multiple ways to breathe. While underwater, the frog's skin grabs oxygen directly from the water. While it's on land, it uses its lungs, but unlike humans, who use the diaphragm muscle to pull air in, the frog has to puff out its throat to get the air in. This is what causes the iconic frog ribbit.
Fish have gills, which are specialized structures that extract oxygen from water as it flows over them. Gills are made up of thin filaments with a rich blood supply that allows for the exchange of oxygen and carbon dioxide. Fish use their gills to absorb oxygen from the water and release carbon dioxide.
Without plants you'd have only primitive life forms ... like the ones that congregate around hot springs deep in the oceans.There would probably be others, such as anaerobic bacteria like the ones that cause gas-gangrene and lock-jaw.* OR *Today's non-oxygen-breathing organisms may only be primitive because they never got a chance to develop.The simple oxygen-breathing organisms of ancient times developed into modern people and all the animals.If the non-oxygen-breathing organisms had not been almost wiped out when plants started 'poisoning' their atmosphere, maybe they would have been the ones who developed into 'people' and all the modern animals.(Except that oxygen based life has more pep, so maybe not!)
Humans take in oxygen through the process of breathing. When inhaling, air enters the lungs and oxygen is absorbed into the bloodstream through tiny air sacs called alveoli. This oxygen is then transported by red blood cells to cells throughout the body for energy production.
Inward only.
Only if you like breathing.
No, the human body needs a balanced mixture of gases to function properly. While oxygen is essential for respiration, breathing in only oxygen without other gases like nitrogen would lead to serious health issues such as oxygen toxicity.
Respiration supplies energy to cells by breakdown of oxygen so is only interacts internally. Breathing is the net movement of gases in and out of the body. The difference is that respiration provides energy for work while breathing provides the reactant for respiration.
Breathing is the only process where exchange of oxygen and carbon dioxide occurs. Oxygen is being delivered to the body parts where oxygen is needed, whilst removing carbon dioxide.
Breathing is the process in which living organisms take in oxygen and give out carbon dioxide.Respiration is the process in which the glucose is burnt in the presence of oxygen to produce carbon dioxide, water and energy .Breathing takes place outside the bodyRespiration takes place inside the bodyDuring breathing we only take air in through our nose and breathe it out.But during respiration the breaking down of food in the presence of oxygen takes place.
we only inhale only oxygen becuse in our lungs only hole of oxygen molecule while other gases can not be in and exhale through mouth
Breathing faster will only drag more oxygen into the lungs, but to get more oxygen to the muscles it has to be picked up and carried into the body by the blood. So the heart has to pump more too, tho move the oxygen from the lungs to the muscles.
Because of our lungs are not capable of breathing in water because of the lack of oxygen and the density of water Because of our lungs are not capable of breathing in water because of the lack of oxygen and the density of water

If you hyperventilate you are most likely to raise blood oxygen to a level too high for your body to cope with. Breathing into and out of a paper bag will lower your oxygen to safer levels because you are now breathing carbon di-oxide. A few minutes 2/3 only or you will lower oxygen to much.
