This condition results in fluid-filled alveoli. What is it?

The condition that results in fluid-filled alveoli is pulmonary edema. This occurs when excess fluid accumulates in the air sacs (alveoli) of the lungs, which can significantly impair gas exchange, leading to difficulty in breathing and a reduction in oxygen levels in the blood.

Pulmonary edema can be caused by various factors, primarily heart-related issues, such as congestive heart failure. When the heart is unable to efficiently pump blood, pressure can build up in the blood vessels of the lungs, causing fluid to leak into the alveoli. Additionally, other causes such as pneumonia, exposure to toxins, or certain medications can also lead to the development of pulmonary edema.

In contrast, emphysema primarily involves the destruction of the alveoli, leading to decreased surface area for gas exchange and is often a result of long-term smoking. Pleurisy is an inflammation of the pleura (the membranes surrounding the lungs) and does not specifically involve fluid in the alveoli. Cystic fibrosis is a genetic disorder that can lead to thick mucus buildup in the lungs, obstructing airways, but does not directly cause fluid-filled alveoli like pulmonary edema does. Thus, the understanding of pulmonary edema is crucial in recognizing how fluid accumulation affects breathing and overall
