CO2.
Oxygen decreases after diffusion into the blood and CO2 being released in respiration is expired in greater concentrations.
Carbon dioxide (CO2).
Nitrogen is the most abundant gas in the atmosphere ( ~ 80% ) and therefore is the dominant species in both inspired as well as expired air.
Exhaled air has less oxygen than inhaled air.Exhaled air has more carbon dioxide than inhaled air.Exhaled air is warmer that inhaled air.Maybe the first 2 are redundant, but I think that should work!
Exhaled air, which has a slightly higher amount of carbon dioxide, is heavier than inhaled air.
Inhaled air contains more oxygen than exhaled air. When you breathe in, oxygen is taken into your lungs and absorbed into your bloodstream. When you breathe out, you release carbon dioxide produced by your body and some of the oxygen has been used up.
exhaled water vapor will be greater than inhaled water vapor
Inhaled air has more oxygen compared to exhaled air. When we inhale, we take in fresh oxygen from the environment to use for cellular respiration. As we exhale, we release carbon dioxide and the remaining oxygen that was not used by the body.
Carbon dioxide is exhaled more than it is inhaled, as it is a waste product of metabolism. Nitrogen is also exhaled more than it is inhaled because it makes up a large percentage of the air we breathe, but is not used by our bodies.
No, argon makes up a very small percentage of both inhaled and exhaled breath, around 0.93% in the atmosphere. The composition of argon in exhaled breath is almost the same as in inhaled breath, as we do not metabolize it.
Yes
Exhaled air has higher levels of carbon dioxide and lower levels of oxygen compared to inhaled air. This is because the body takes in oxygen from the air and releases carbon dioxide as a waste product during the process of respiration.
Exhaled air should have less oxygen since it is carrying the CO2 from your lungs in the first place. A way of showing... there may be
