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 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!
Yes
Air in the atmosphere is a mix of about 78% nitrogen, 20.95% oxygen, 0.93% argon, and 0.038% carbon dioxide (CO2) When air is breathed in (inhaled) oxygen is absorbed by the lungs, exchanging it for waste carbon dioxide, carrying the CO2 away from the body when exhaled. Exhaled air has a CO2 content of about 5%, i.e. 125 times more CO2 than 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.
Inhaled gases is oxegen and exhaled gases you CAN'T brethe in because it's carbon dioxide.
Exhaled air, which has a slightly higher amount of carbon dioxide, is heavier than inhaled air.
Breathing.

Exhaled air contains CO2 (Carbon Dioxide) and Inhaled air contains O2(Oxygen).
yes it is the inhaled air is 0.04 %, whereas, of the exhaled air is 4 % (100 times) more

Nitrogen is a gas that is present in the same concentration in inhaled and exhaled air, as it is not chemically changed by the body during respiration.

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.

Either through the nose or the mouth
The bronchioles carries inhaled and exhaled air to and from the alveoli.
