Membranes within Cavities

These flashcards cover key concepts related to the types of membranes within body cavities, including their functions and locations.

Mucous Membrane

Produces mucous, a thick, sticky fluid that may be clear, yellow, or greenish.

Serous Membrane

Produces serous fluid, a thin, watery fluid that provides lubrication and decreases friction.

Parietal Layer

Lines the inside walls of cavities.

Visceral Layer

Lines the organs within cavities.

Cavity

The space between the visceral and parietal membranes.

Mucous Production

Mucous membranes line passageways that are open to the exterior, such as those in the digestive, respiratory, urinary, and reproductive tracts.

Serous Fluid

Fluid that decreases friction between the movements of visceral organs in thoracic and abdominopelvic cavities.

Structure of the Body

The body is made up of atoms.
