Pleural effusion, also called âwater on the lung,â is an excessive buildup of fluid between your lungs and chest cavity. Thereâs always a small amount of liquid inside your lungs.This fluid works to coat the membranes (pleura) that line the outside of your lungs and lubricate the chest cavity to aid in breathing.he pleura creates too much fluid when itâs irritated or infected. This fluid accumulates in the chest cavity outside the lung, causing whatâs known as pleural effusion. Certain types of cancer, such as lung, breast, and ovarian cancers, can cause pleural effusions. Lymphoma and mesothelioma can cause them too.
The pleura (the covering of the lungs). There are 2 fibrous sheets of tissue that cover the lungs and help to protect them. These are callled the pleura or pleural membranes. Doctors usually call these the lining of the lungs, although this can be a bit confusing as they are on the outside.The gap between the pleura is called the pleural space.lose to the lungs and airways are lymph nodes (also called lymph glands). They are small bean shaped glands found throughout the body. They are connected by a network of tubes called lymphatics or lymphatic vessels. This network carries a fluid that leaks out of the blood vessels and bathes the body tissues and cells.
