pleura

To check for them, doctors look at the pleura, the membrane that envelops each lung.

“But because his surgeon . said it had spread to the pleura of the lungs, they said it wasn’t a covered cancer.”

It can detect blockage and constriction in arteries and veins, and can identify issues in the pleura, the fluid-filled membranes that line the thorax and lungs.

In short, an abscess in the pericardium must be treated like an abscess in the pleura.

To stick fast or cleave, as a glutinous substance does; to become joined or united; as, wax to the finger; the lungs sometimes adhere to the pleura.
