Final answer:
Fluid buildup in the lungs, known as pulmonary edema, typically occurs due to heart failure but can also result from genetic conditions like cystic fibrosis or infections like pneumonia. It can cause severe respiratory issues and requires immediate medical attention.
Step-by-step explanation:
When fluid buildup occurs in the lungs, this condition is known as pulmonary edema. This can result from heart failure, where the heart is unable to pump blood effectively, causing fluid to back up into the pulmonary capillaries and leak into the lung tissues. Pulmonary edema can lead to symptoms like difficulty breathing, chest pain, and it can be life-threatening as it impairs gas exchange in the lungs. Another possible cause is cystic fibrosis, which is a genetic condition that produces thick mucus blocking the lungs and can interfere with digestion and nutrient absorption.
Conditions such as pneumonia also contribute to fluid accumulation in the lung alveoli, leading to similar respiratory difficulties.As a result, fluids get backed up in the pulmonary capillaries, causing increased hydrostatic pressure and fluid to be pushed into lung tissues. This can lead to difficulty breathing, chest pain, and compromised gas exchange in the lungs, which is a serious condition and requires immediate medical attention.
