There are a number of gases that enter and leave the lungs - predominantly, humans Inspire (Breathe in) Oxygen and Expire (Breathe out) Carbon Dioxide.

Two main gases exchange in the lungs: oxygen and carbon dioxide.
Oxygen and carbon dioxide
The carbon dioxide and oxygen are the two main gases in plasma. When blood travels to the lungs the concentration of these two gases changes.
The human respiratory system contains two lungs, symmetrically arranged in the chest, the trachea, which leads from the lungs to the mouth and nose. This simple arrangement allows humans to breathe.
oxygen and carbon dioxide
Oxygen and carbon dioxide in the alceoliCO2 and O2
Air can enter the body by the mouth or the nose. Air then goes down the windpipe to the lungs where it can enter the bloodstream.
Oxygen and carbon dioxide increase and decrease in the lungs.
Primary brochi first enter the lungs on both the left and right sides.
the trachea is air passage tube that allows air to enter your lungs. the bronchi are two little tubes that are connected to the end of your trachea and lead to the lungs.
Carbon Dioxide (CO2) and Oxygen (O2) can enter leaves through the pore.
During the breathing process, the two gases exchanged are oxygen and carbon dioxide. Oxygen is inhaled into the lungs and then transferred into the bloodstream, while carbon dioxide is carried from the bloodstream into the lungs to be exhaled.
