The gases get into your lung when you breathe.
Not for mild interstitial lung disease. However, if it becomes severe, limiting the ability of the lung to do any useful work of breathing (oxygen in and CO2 out), then a lung transplant may be the only thing that will help.
bronchi provides air to the lung. They carry both oxygen and co2.
Bronchi carries air to lung. Mainly o2 and co2.
bronchi and brochioles provide air to the lung. They carry both oxygen and co2.
Intake of oxygen from the outside world carrying it into the bloodstream, and exhalation of CO2.
at a co2 of 100 or so the person will be confused and sleepy. The lungs taking in the oxygen are not exhaling forcefully enough to expel the co2. This is usually due to lung problems such as COPD
Actually bronchi and brochioles provide air to the lung. They carry both o2 and co2.
Humans do, and all animals! We breathe in O2 and breathe out CO2.
CO2 is expired because when you expire your diaphram moves in and up decreasing lung volume, thus increasing the concentration of CO2 in the lungs. Then diffusion naturally occurs and the CO2 is expired and O2 is then inspired.
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.
