Transcellular fluid

Transcellular Fluid

Transcellular fluid (pronunciation: trans-sel-yuh-ler floo-id) is a component of the body fluids that is contained within epithelial lined spaces. It is the smallest portion of the extracellular fluid, which also includes interstitial fluid and plasma.

Etymology

The term "transcellular fluid" is derived from the Latin word "trans" meaning "across", and "cellular" from the Latin "cellula" meaning "a small room". Thus, it refers to the fluid that moves across the cellular spaces.

Composition

Transcellular fluid includes the fluids found in specific compartments of the body, such as cerebrospinal fluid, synovial fluid, pericardial fluid, pleural fluid, peritoneal fluid, intraocular fluid, and endolymph and perilymph in the inner ear.

Function

The primary function of transcellular fluid is to aid in the transportation of substances between cells and to help maintain the homeostasis of the body. It also serves as a lubricant in the pleural, pericardial, and peritoneal cavities, and provides a medium for the absorption and transport of nutrients in the gastrointestinal tract.
