Explain how tobbaco smoke hinders the lungs ability to eliminate foreign stubstances?

Answer 1

what tobacco smoke does is deteriorate the walls in your aveolli (small clustered sacks in your lungs that exchange oxygen and carbon dioxide). when those walls are damaged if become harder and harder for the lungs to exchange gases, almost like your being suffocated. this weakens your lungs and they cant fight off infections. when they get weakened to the point where the patient has too minumal of gas exchange its called emphazima. the reason you see people with emphazima walking around with oxygen tanks is because they need high concentrates of o2 in order to stabilize the gas exchange in their deteriorated aveollis. Most people with Emphizema die of pnuemonia, in short they basically suffocate to death.
