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

Noun
- the process of exuding; the slow escape of liquids from blood vessels through pores or breaks in the cell membranes
