The spelling of "pleura pulmonalis" can be a bit tricky as it includes a combination of Latin and Greek roots. "Pleura" comes from the Greek word "pleurē" meaning "side," while "pulmonalis" comes from the Latin "pulmo" meaning "lung." The correct pronunciation can be achieved by breaking down the word into syllables: "pleur-a pul-mo-na-lis." It is pronounced [plʊərə pʊlməˈneɪlɪs], with the emphasis on the third syllable. This word refers to the membrane that covers the lungs and lines the chest cavity.
Pleura pulmonalis refers to the two thin membranes that surround the lungs, specifically the outer layer of the lungs known as the visceral pleura. The word "pleura" originates from the Greek word "pleura" meaning "side," "rib," or "flank," while "pulmonalis" is derived from the Latin word "pulmo" meaning "lung."
The pleura pulmonalis is composed of two layers: the visceral pleura, which attaches directly to the lungs, and the parietal pleura, which lines the inner chest wall surrounding the lungs. These layers are separated by a small space known as the pleural cavity, which contains a thin layer of lubricating fluid called pleural fluid. The pleural fluid assists in reducing friction between the lungs and the chest wall during breathing, allowing for smooth movement.
The main function of the pleura pulmonalis is to protect and support the lungs. It acts as a barrier between the organs and the chest cavity, preventing the lungs from rubbing against the chest wall. Additionally, the pleura pulmonalis assists in maintaining lung inflation by transmitting the forces generated during breathing. It also provides a mechanism for the exchange of gases between the air in the lungs and the bloodstream, aiding in respiration.
In summary, the pleura pulmonalis refers to the thin membranes that envelop and protect the lungs, consisting of the visceral and parietal pleura layers. It provides essential support and facilitates proper lung function, while serving as a protective barrier and aiding in the exchange of gases during respiration.

The term "pleura pulmonalis" is a combination of two words.
1. "Pleura" comes from the Greek word "pleura" meaning "side" or "rib". In anatomy, it refers to the thin, double-layered membrane that covers the lungs and lines the chest cavity.
2. "Pulmonalis" is derived from the Latin word "pulmo" meaning "lung". It is used to indicate something related to the lungs.
Therefore, "pleura pulmonalis" is a combination of "pleura" (referring to the membrane covering the lungs) and "pulmonalis" (indicating a relation to the lungs).
