The pleura includes two thin layers of tissue that protect and cushion the lungs . The inner layer (visceral pleura) wraps around the lungs and is stuck so tightly to the lungs that it cannot be peeled off. The outer layer (parietal pleura) lines the inside of the chest wall.
What is the pleura of the lungs?
The chest cavity is lined by a thin shiny membrane called the pleura, which covers the inside surface of the rib cage and spreads over the lungs as well. Normally, the pleura produces a small amount of fluid which serves as a lubricant to the lungs as they move back and forth against the chest wall during respiration.
What is pulmonary pleura?

Where is the pulmonary pleura?
Your pleura is a large, thin sheet of tissue that wraps around the outside of your lungs and lines the inside of your chest cavity. Between the layers of the pleura is a very thin space.
What are the two pleura?
There are two layers; the outer pleura (parietal pleura) is attached to the chest wall and the inner pleura (visceral pleura) covers the lungs and adjoining structures, via blood vessels, bronchi and nerves.
Do lungs help blood get around your body?
Blood with fresh oxygen is carried from your lungs to the left side of your heart, which pumps blood around your body through the arteries . Blood without oxygen returns through the veins, to the right side of your heart.
Does the pleural cavity contain the lungs?
The pleural cavity surrounds the lungs in the thoracic cavity . There are two pleural cavities, one for each lung on the right and left sides of the mediastinum. Each pleural cavity and it’s enclosed lung are lined by a serous membrane called pleura.
What diseases cause pleurisy?
What causes pleurisy? Most cases are the result of a viral infection (such as the flu) or a bacterial infection (such as pneumonia). In rarer cases, pleurisy can be caused by conditions such as a blood clot blocking the flow of blood into the lungs (pulmonary embolism) or lung cancer.
Is pleurisy considered a lung disease?
Pleurisy (PLOOR-ih-see) is a condition in which the pleura — two large, thin layers of tissue that separate your lungs from your chest wall — becomes inflamed . Also called pleuritis, pleurisy causes sharp chest pain (pleuritic pain) that worsens during breathing.
Is pleurisy a lung disease?
Pleurisy happens when the membrane, or pleura, that lines the inner side of your chest cavity and surrounding lung tissue becomes inflamed . This is commonly a result of a lung or respiratory infection. Symptoms include sharp chest pain. This pain is often worse with deep breathing, coughing, or sneezing.
How long can you live with pleural effusion?
Patients with Malignant Pleural Effusions (MPE) have life expectancies ranging from 3 to 12 months , depending on the type and stage of their primary malignancy.
Are lungs muscular?
The lungs have no skeletal muscles of their own . The work of breathing is done by the diaphragm, the muscles between the ribs (intercostal muscles), the muscles in the neck, and the abdominal muscles.
What happens to the pleura during normal ventilation?
The pleura
Between the two layers is the intrapleural space, which normally contains fluid secreted by the membranes. This allows the two layers to slide easily over one another as the lungs inflate and deflate during respiration .
How are lungs protected?
Your lungs are protected by your rib cage , which is made up of 12 sets of ribs. These ribs are connected to your spine in your back and go around your lungs to keep them safe.
What is the mediastinal pleura?

What is the main cause of emphysema in a human being?
What causes emphysema? Smoking is the number one factor. Because of this, emphysema is one of the most preventable types of respiratory diseases. Air pollutants in the home and workplace, genetic (inherited) factors (alpha-1 antitrypsin deficiency), and respiratory infections can also play a role in causing emphysema.
