The Nitrogen we breathe IS absorbed by the blood vessels (and all the body tissues). While the Nitrogen gas from the air is inert and does not play any part in body processes, Henry's gas laws require that some of the Nitrogen will be absorbed/dissolve in the blood (and body tissues). This becomes an issue for sub aqua divers where the presence of this dissolved nitrogen causes the "bends".
because the haemoglobin present in our blood has no capacity to absorb nitrogen so the result is that the nitrogen is not absorbed and you breathe out the same amount of nitrogen as you breathed in.......
Here the main function is of lungs and blood vessels.When we breathe oxygen from atmosphere get into our lungs and is absorbed into blood vessels in our lungs and these blood vessels transport oxygen to our toes from where carbon dioxide is absorbed into blood vessels and oxygen is provided to the tissues and this process goes on.
You breathe in air, which is comprised mostly of nitrogen (though the oxygen is what you're after).The oxygen is absorbed into the blood, and stored in red blood cells, which contain hemoglobin.The oxygen in your lungs is thus replaced mainly by carbon dioxide, which is a metabolic waste product, and this is what you breathe out.
yep
it is not absorbed because of dead cells, or pathogen!
You would be called a dead person because, without blood vessels, your blood can't travel, and if your blood can't travel, you can't breathe, and if you can't breathe, you will die.

The oxygen in the air you breathe in is absorbed via the lungs into the blood.
Blood Vessels
Oxygen is in the air, and when you breathe in the oxygen gets into your lungs and is absorbed into the red blood cells.
Yes, the vessels inside your nose warm the air you inhale.
The nutrients that are absorbed through the villi are transfered to the blood stream where it can be transfered to other parts of the body. So the vessels enable the villi to transfer nutrients to the blood system. = 0
