When you breathe in oxygen you expel carbon dioxide, your bodies waste product. Your heart pumps blood from the right ventricle into the lungs where the CO2 (carbon dioxide) "jumps off" and the O2 (oxygen) "jumps on" the red blood cells. With the O2 being carried on little "handles" of the hemoglobin molecule of the red blood cells, it travels back into the heart from the lungs and is then pumped out into the body from the heart's left ventricle, through the aorta and into the body. The O2 is carried by the blood to every area and organ of the body, where it "nourishes" the cells. As the blood travels further from the heart and more waste builds, the CO2 content is higher than the O2 content and the CO2 waste is carried back to the heart by the blood, dumping its waste into the lungs and is then expelled in your breath. This gas exchange is made possible because of changes in pressure gradients.
When you inhale, you breath in oxygen and your lungs get bigger.
then we could not breath.
We have trees so we can breath and that happens because when we breath in all the oxygen comes inside us and when we breath out all the oxygen comes out of us.
we and the animals breath it.
breath in breath out breath in breath out
well if muscles run out of oxygen you might slow down and not breath proppely and you might also die.
You will trigger a panic attack. (I have them all the time). To prevent them, breath into a bag, the carbon is to limit the intake of oxygen. Too much oxygen can be a bad thing, strange but true. But I don't think it effects dogs, if it's repetative you might want to take him/her to the vet.
we breath in mostly oxygen when we breath and when that oxygen goes to our lungs it goes through the bronchi and into little air sacs called alveoli the oxygen then moves into the blood going into the red blood cells while at the same time carbon dioxide moves out of the blood and comes out of body as exhales air
animals usually depend on plants for oxygen. we breath out carbon dioxide and breath oxygen in, same with animals. and plants breath that carbon dioxide in and and breath out oxygen.
If all the plants in the world die, then we could'nt breath, because no oxygen would be produced
we breath in oxygen and plants breath co2
We get Oxygen from atmosphere.It is in air we breath.
