Question

“Emphysema” is a condition in which
A. Respiratory center is inhibited
B. Lots of fluid in the lungs
C. The walls separating the alveoli break
D. Lungs have excess O2

Answer 1

In emphysema, the walls between many of the air sacs in the lungs are damaged. This causes the alveoli to lose their shape and become floppy. The damage also can destroy the walls of the alveoli, leading to having some and large-sized alveoli instead of many tiny ones.

Complete step by step answer: The main cause of emphysema is long-term exposure to airborne irritants like tobacco smoke, marijuana smoke, air pollution, chemical fumes, and dust. If left untreated, emphysema can develop into serious complications, such as holes in the lungs (giant bullae). These large holes make it difficult for your lung to expand. They can also get infected and may lead to a collapsed lung. Symptoms of emphysema include coughing, wheezing, shortness of breath, chest tightness, and increased production of mucus. some times until 50 percent or more of the lung tissue has been destroyed, the symptoms may not be noticed. A blood test can detect the early development of emphysema before symptoms become apparent.
Hence, the correct option is C, i.e., The walls separating the alveoli break.

Note: If a person has advanced emphysema, the doctor may notice that a person has any of the following: He/she has a barrel chest caused by larger-than-normal lungs, wheezing, having a hard time getting air out of the lungs had exhaled air from the lungs, fingertips are round and Doctors call this clubbing. Emphysema can't be cured, but treatments can help relieve symptoms and slow the progression of the disease. Walking is a safe and effective form of exercise for nearly everyone, including people living with chronic obstructive pulmonary disease (COPD).
