1.	Emphysema is marked by ______(a) inflammation of nasal passage(b) twisting of trachea(c) filling of mucous in lungs(d) damage of alveolar wallsI have been asked this question in homework.Question is from Disorders in Respiratory System topic in section Breathing and Exchange of Gases of Biology – Class 11
Answer» The correct option is (d) damage of ALVEOLAR walls To elaborate: Emphysema is a CHRONIC disorder which is marked of damage of alveolar walls. This leads to inadequate supply of oxygen to the BODY parts. The most common cause FOUND so far is CIGARETTE smoking.
