Final answer:
The removal of infected tissue stems the infection by eliminating the area where pathogens can proliferate, thus reducing the spread to healthy tissue and aiding the immune system. Most pulmonary disease is not typically surgically removable, with surgery reserved for localized infections or areas of damage.
Step-by-step explanation:
The removal of infected tissue can stem the infection because it eliminates the area where pathogens proliferate and cause damage. When infected tissue is present, it acts as a reservoir for the infectious agents, allowing them to continue to reproduce and spread. By surgically removing this tissue, you remove the source of the infection, which helps to stop the spread of the infection to healthy tissues. It also helps to reduce the load on the patient's immune system, allowing it to better manage and clear any remaining infection.
In terms of pulmonary disease, surgical removal is often possible in the case of localized infections or conditions such as lung abscesses or localized areas of damage from conditions like emphysema. However, it's essential to note that not all pulmonary diseases are surgically removable. Conditions such as Chronic Obstructive Pulmonary Disease (COPD) or asthma are managed with medications and lifestyle changes rather than surgery.
