Final answer:
When fluid collects in the pleural space surrounding the lungs, it is called Pleural effusion. Thus the correct option is A.
Step-by-step explanation:
Pleural effusion refers to the accumulation of fluid in the pleural space, the area between the layers of tissue that line the lungs and the chest cavity. This condition can result from various causes such as infections, heart failure, cancer, or inflammation. When fluid collects in this space, it can compress the lungs, leading to difficulty in breathing and discomfort.
To understand pleural effusion, it's crucial to recognize the dynamics of the pleural space. Normally, a small amount of fluid is present to lubricate the surfaces, allowing smooth movement during breathing. However, an imbalance in fluid production and removal due to underlying health issues can cause an excess buildup, leading to pleural effusion. Diagnosis typically involves imaging tests like chest X-rays or ultrasounds and may require further analysis of the fluid itself through procedures like thoracentesis.
The treatment of pleural effusion depends on its underlying cause. It might involve addressing the root condition, draining the accumulated fluid, or using medications to alleviate symptoms and prevent recurrence. Managing the cause is essential for effective treatment and preventing complications related to compromised lung function due to the presence of excess fluid in the pleural space.Thus the correct option is A.
