Respiratory distress can occur if which structures collapse?

Respiratory distress can occur when the alveoli collapse because they are critical for gas exchange in the lungs. The alveoli are tiny air sacs where oxygen and carbon dioxide are exchanged between the air we breathe and the blood. If the alveoli collapse, a condition known as atelectasis, it significantly reduces the surface area available for this gas exchange, leading to decreased oxygen levels in the blood and an accumulation of carbon dioxide. This compromised ability to exchange gases can result in symptoms of respiratory distress, such as shortness of breath and an increased heart rate. Maintaining the integrity of the alveoli is essential for proper respiratory function, making their collapse a critical issue in respiratory health.
