Air goes into the nose and then through the trachea.
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!
It is because, once the air is inhaled, the lungs absorb the oxygen in the air and releases only the remaining stale air. The air that goes in has a higher % of Oxygen and the air that comes out has a higher % of Carbon di oxide.
Inhaled air contains a greater volume of oxygen than carbon dioxide. Exhaled air is the opposite, since after the exchange of gases in the lungs the carbon dioxide in the blood is transferred into the lungs. Exhaled air contains a greater volume of carbon dioxide than oxygen. Also, there is more water vapour in exhaled air than inhaled air.
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
Air inhaled through the mouth is not as clean as air inhaled through the nose. Reason for this is that when we inhale air through our nose than it get filtered by hair present in our nose. But air inhaled through our mouth goes directly in without any filtration.
Inhaled air is warmed and moistened in the nasopharynx and oropharynx.
Inhaled air is typically warmed and humidified as it passes through the nasal passages. The purpose of this process is to protect the delicate tissues of the respiratory system from damage due to cold and dry air.
Air is inhaled through the nose (nasopharynx) or mouth (oropharanx) and travels down the pharynx past the epiglotis and into the larynx. Then down into the Trachea where it meets the Carina and goes either right or left into the Broncus. Then down to the Bronchi and finally the alveoli where gas exchange takes place with the pulmonary capilaries.
Exhaled air, which has a slightly higher amount of carbon dioxide, is heavier than inhaled air.
Nitrogen is not used by the body; oxygen is taken in and carbon dioxide and water goes out.
It is because, once the air is inhaled, the lungs absorb the oxygen in the air and releases only the remaining stale air. The air that goes in has a higher % of Oxygen and the air that comes out has a higher % of Carbon di oxide.
Exhaled air contains 16% oxygen and 21% when inhaled.
Inhaled air contains a greater volume of oxygen than carbon dioxide. Exhaled air is the opposite, since after the exchange of gases in the lungs the carbon dioxide in the blood is transferred into the lungs.
