Which of the following organs is most likely affected by the accumulation of air due to pneumothorax?

Explanation:
The accumulation of air in the thoracic cavity due to a pneumothorax primarily affects the lungs. In a pneumothorax, air enters the pleural space— the area between the lung and the chest wall— which can lead to lung collapse. This condition can impede the lung's ability to expand during inhalation, leading to reduced oxygen exchange and compromising respiratory function. The lung is directly adjacent to the pleural space, making it the organ most vulnerable during a pneumothorax. The heart, spleen, and kidneys, while important organs, are not situated in a way that they would be affected by the accumulation of air in the pleural space. Although they are part of the body and vital for general health, their functions and conditions are not altered directly by a pneumothorax incident.
