What other places in the human body other than the Lungs and Heart is oxygen stored?
Lungs maybe
What is another way amphibians can obtain oxygen other than gills and lungs?
through there skin.....
Is it true that a cow's lungs is bigger than a humans lungs?
Yes. Cows are much larger than humans are, thus need more oxygen to take in in order to function.
Oxygen diffuses into the capillaries of the lungs because there is a?
greater concentration of oxygen in the air sacs of the lungs than in the capillaries.
Why do you have 2 lungs?
So your lungs can create oxygen in your blood quicker than if there were just one.
How your lungs refine oxygen from other gases?
Your lungs refine oxygen from the other gases in air because the gases diffuse through the cell walls in the alveoli in your lungs through osmosis (higher concentration of gases in the air than in the blood, so gases move from the higher concentration to the lower concentration) where they contact the red blood cells. The hemoglobin in the red blood cells binds to the oxygen and leaves all the other gases alone. It moves on from the lungs and delivers the oxygen to the rest of the body. It's the hemoglobin that does the work.
Which one of your organs do not need oxygen?
ALL of the the organs in the human body need an oxygen supply. This even includes the organs responsible for delivering oxygen to the rest of the body: the heart and lungs. Every organ requires oxygen. All that can be said in this case is that some organs use/need more oxygen than others. For instance, the brain needs/uses more oxygen than the spleen.
Why is oxygen more important than the other elements?
Oxygen is what humans breathe in. We need it to be alive.
Oxygen diffuses into the capillaries of the lungs because there is?
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
What is another example of diffusion other than osmosis?
The transfer of oxygen from the alveoli into the capillaries in the lungs, and the transfer of carbon dioxide from the capillaries into the alveoli (i.e. breathing in, and the oxygen going into the blood, and carbon dioxide going into the lungs to be expelled when we breathe out).
Why does air move in the lungs?
We breath because the oxygen/CO2 levels in our lungs are less than that of our surroundings. When you breathe in, your lungs expand and allow more oxygen to flow in. When you exhale, the CO2 levels in your lungs is greater than the your surroundings, so the CO2 leaves and the process repeats itself. This is called negative pressure breathing.
Why does the air in the lungs have a lower percentage of oxygen and higher carbon dioxide than the inspired air?
Because your body consumes the oxygen and generates carbon dioxide as a waste product. Extracting oxygen and emitting carbondioxid is what the lungs are for.
