Why does a human being not absorb any argon while breathing? Same rate as inhaled and exhaled breath.?

Question

Most of the other elements found in air are absorbed while inhaling. Argon stays at the same percentage. I was wondering why this was.

Answer 1

metatron has a pretty good answer. Argon may be absorbed into the bloodstream, but since it doesn't react (as does oxygen) in the body, it remains unchanged, so there's no net change in percent argon in the inspired versus the expired air.

What may change are the exact atoms in the air stream -- but the only way you'd be able to track that would be to use a radioactive isotope and track the distribution of the isotopic mixture.

Answer 2

Argon is one of the inert or noble elements characterized be having a complete outer electron shell. Having a complete outer shell means that a noble element is not looking for any more electrons or willing to give up any electrons. What this means is Argon will not react with any thing under normal conditions (as long as it maintains its atomic structure).

Answer 3

The simple answer is that argon is very unreactive, so it doesn't react with anything in our body, so the argon atoms are free to leave our bodies again when we exhale.

Answer 4

Argon is totally inert: it will not combine with any chemicals in the body (or anywhere else). It is not particularly soluble in blood, and will go out of solution as quickly as it goes in. Hence, no absorption.

Answer 5

molecules must have places that argon fits to connect to in order to be retained by the body.

Answer 6

argon is an inert gas and cannot be absorbed into human cells...

Answer 7

......more than very unreactive, it is totally inert, so cant combine with anything inside or outside your body. What goes in must come out.
