transudation

A clear fluid undergoes transudation from the capillaries into the surrounding tissue.

Definition
  1. Noun:
    • The process of passing through a membrane or tissue: "transudation" refers to the slow movement of fluid, typically from blood vessels, through pores or small openings in a membrane, without causing damage to the cells.
    • The fluid that has passed through: "transudation" can also refer to the substance itself that has oozed or filtered through.
Usage
  • As a process:
    • The transudation of plasma into the interstitial space is a normal physiological process.
    • Edema can result from increased transudation of fluid from capillaries.
  • As a substance:
    • The clear fluid on the surface of the blister was a transudation.
    • Analysis of the transudation revealed a low protein content.
Advanced Usage
  • Medical/Physiological Context: The term is primarily used in medical, biological, and physiological contexts to describe non-inflammatory fluid movement, often contrasted with "exudation," which involves inflammation and higher protein content.
    • The distinction between a transudate and an exudate is crucial for diagnosing the cause of pleural effusion.
Variants and Related Words
  • Transude (verb): To pass or ooze through pores or interstices.
    • Fluid can transude through the capillary walls.
  • Transudate (noun): The fluid product of transudation.
    • A transudate is typically clear and has low cellular content.
Synonyms
  • Oozing: The process of slowly leaking out.
  • Seepage: The slow escape of a liquid through porous material.
  • Filtration: The process of passing a liquid through a filter; in physiology, it can describe a similar passive process.
Antonyms
  • Exudation: The process of discharging fluid, often with high protein and cell content, typically associated with inflammation.
  • Absorption: The process of taking in or soaking up a substance.
Related Phrases/Concepts
  • Capillary filtration: A closely related physiological process describing fluid movement across capillary walls due to hydrostatic and osmotic pressures, often resulting in transudation.
  • Hydrostatic pressure: A primary force driving the transudation of fluid from blood vessels.
