Question

How is it possible to remove a section of lung without damaging neighboring sections?

a) Lungs are actually composed of multiple separate structures each served by its own bronchus.
b) Surgeons cauterize any freshly cut portion of the lung to seal it.
c) It isn't possible to perform this type of surgery on lungs.
d) The bronchopulmonary segments are separated from each other by connective tissue septa.

Answer 1

It is possible to surgically remove a section of the lung without damaging neighboring sections due to the bronchopulmonary segments being separated by connective tissue septa, allowing for targeted surgery on diseased segments.

Step-by-step explanation:

How to Remove a Section of Lung Without Damaging Neighboring Sections

The human lungs are composed of lobes that are separated by fissures, with the right lung having three lobes and the left having two. Each lobe contains multiple bronchopulmonary segments, which receive air from their own tertiary bronchus and are supplied with blood by their own arteries. This anatomical structure allows surgeons to remove a diseased segment with little impact on neighboring segments. The removal is possible because connective tissue septa, or interlobular septa, provide a division between the segments, ensuring they are separate structures that can be individually operated upon.

Therefore, the correct answer is option d) The bronchopulmonary segments are separated from each other by connective tissue septa. This allows for the surgical removal of a specific lung section without significantly affecting the other sections of the lung.

Answer 2

It is possible to remove a section of lung without damaging neighboring sections because the bronchopulmonary segments are separated from each other by connective tissue septa (Option D).

Step-by-step explanation:

Lung sections called bronchopulmonary segments can be surgically removed without harming neighboring sections due to their individual bronchi and blood supply, separated by connective tissue septa. It is possible to remove a section of a lung without damaging neighboring sections because the lungs are composed of bronchopulmonary segments that are each served by their own tertiary bronchus and blood supply.

The bronchopulmonary segments are separated by connective tissue septa, which makes it feasible to remove a diseased segment with little impact on the adjacent healthy segments. Each lung has multiple lobes that house these segments: the right lung consists of three lobes, while the left lung has two. These subdivisions not only allow for targeted surgical intervention but also ensure that the remaining lung tissue can function effectively after surgery.

Thus, the correct option is D.
