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.
Exhaled air has more carbon dioxide and less oxygen than does inhaled air.
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
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 will be of ambient temperature. If the surroundings are warm, then inhaled air is warm. If surroundings are cold then inhaled air is cold.
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
the process in which the inhaled air is used twice for the process of respiration is called double respiration. eg:-in COLUMBA sp.the air when it is inhaled it goes into the lungs,the excess air goes into air sac for temporal storage fron here by recurrent bronchus air is taken back to the lungs completiong double respiration.
Inhaled air is warmed and moistened in the nasopharynx and oropharynx.
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.
Exhaled air contains 16% oxygen and 21% when inhaled.
Nitrogen is not used by the body; oxygen is taken in and carbon dioxide and water goes out.
Exhaled air has more carbon dioxide and less oxygen than does inhaled air.
