Air is inhaled to use the oxygen for cell respiration. Then carbon dioxide and water (products of cell respiration) are breathed out because they are waste products.
Exhaled air, which has a slightly higher amount of carbon dioxide, is heavier than inhaled air.
Breathing.
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 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
Yes
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.
Either through the nose or the mouth
The bronchioles carries inhaled and exhaled air to and from the alveoli.
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.
