Pleural vs. Peritoneum — What's the Difference?

A thin serous membrane in mammals that envelops each lung and folds back to make a lining for the chest cavity.

The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal (or coelomic) organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue.

Either of the two lateral portions of a body segment of an arthropod.

The serous membrane that lines the walls of the abdominal cavity and folds inward to enclose the viscera.

Of, relating to, or affecting the pleura, or the sides of the thorax.

(anatomy) In mammals, the serous membrane lining the cavity of the abdomen and that is folded over the viscera.

Thin and transparent.

(zoology) In animals, the membrane lining the coelom cavity.

Of or pertaining to the pleura or pleuræ, or to the sides of the thorax.

The smooth serous membrane which lines the cavity of the abdomen, or the whole body cavity when there is no diaphragm, and, turning back, surrounds the viscera, forming a closed, or nearly closed, sac.

Of or relating to the pleura or the walls of the thorax;

A transparent membrane that lines the abdominal cavity in mammals and covers most of the viscera
