the best answer is:Smoking reduces the gases in oxygen
The efficiency of gas exchange in the lungs of vertebrates is greater because it increases the lungs' internal surface area.
the tar like substance prevents your lungs from taking in enough oxygen.
The lungs are the primary organ affected by emphysema.
Emphysema
Yes, emphysema can decrease respiratory volume by damaging the air sacs in the lungs, which reduces the lungs' ability to efficiently exchange oxygen and carbon dioxide. This damage can lead to symptoms such as shortness of breath and decreased exercise tolerance.
Emphysema can be associated with a respiratory acidosis, where the lungs are unable to expel enough carbon dioxide, leading to an accumulation of acid in the blood. This occurs due to the reduced ability of the damaged alveoli in the lungs to exchange gases effectively.
emphysema
The person's lungs are not moving air well in emphysema. Also irritants cause increased production of phlegm, which can reduce air movement, hence, diminished breath sounds.
Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli (air sacs in the lung). In people with emphysema, the lung tissue involved in exchange of gases (oxygen and carbon dioxide) is impaired or destroyed.Source: emedicinehealth :)
Tar, which is a sticky substance found in cigarette smoke, can accumulate in the lungs and airways of smokers. It can coat the alveoli, where gas exchange occurs, leading to decreased surface area for oxygen and carbon dioxide exchange. This can impair the efficiency of gas exchange and reduce the amount of oxygen that reaches the bloodstream.
