oxygen gas
carbon dioxide
They all enter the lung ... but the only one that quickly enters the blood is oxygen. Because oxygen is the one gas that has a higher partial pressure in "lung air" than its partial pressure in the "lung blood". Note that the blood's CO2 pressure is higher than the air in the lungs, so CO2 comes out of the blood into the lung's air.
Mainly carbon dioxide.
nothing, absolutely nothing, nitrogen gas is 70% of the earth's air, it enters our body 30% and goes out 30%.
Arterial blood gas. It checks blood gas levels (oxygen, carbon dioxode, and bicarbonate) and blood pH.

The gas that enters the atmosphere during the light reaction is oxygen (O2). Oxygen is produced as a byproduct when water is split during photosynthesis.
somthing oxide
co2
carbon dioxide
the answer is quite simple ...... carbon dioxide is the waste gas and it leaves the blood and then leaves the body when you exhale.
The Process of the Respiratory System I am a Respiratory Therapist, so this is easy for me. During inspiration, air(gas) enters either through the nose or the mouth. As the air reaches the throat it becomes warmed and humidified and then passes into the trachea. It follows the trachea down into the bronchi then to the bronchioles(smaller versions of the bronchi) then into the alveoli. The alveoli are tiny sacs at the end of the bronchioles that look like clusters of grapes. After the air(gas) enters the alveoli, the oxygen from the air crosses the alveolar-capillary membrane and enters the blood. The blood then carries the oxygen to the organs of the body. During expiration, as the oxygen in the alveoli is entering the blood, carbon dioxide leaves the blood, enters the alveoli and is breathed out.
It is carbon dioxide which is collected from different organs of the body by blood
The function of the respiratory system is to provide the body with oxygen. Oxygen enters the body through the respiratory system and is carried in blood throughout the body.
Oxygen in the lungs and passes through the alveoli, small sacs which allow gas exchange, and enters the blood to be pumped throughout the body.
