Effusion vs. Edema — What's the Difference?

The effused fluid.

A similar swelling in plants caused by excessive accumulation of water.

In physics and chemistry, effusion is the process in which a gas escapes from a container through a hole of diameter considerably smaller than the mean free path of the molecules. Such a hole is often described as a pinhole and the escape of the gas is due to the pressure difference between the container and the exterior.

Same as œdema.

The act or an instance of effusing.

Edema, also spelled oedema, and also known as fluid retention, dropsy, hydropsy and swelling, is the build-up of fluid in the body's tissue. Most commonly, the legs or arms are affected.

The act of pouring out; as, effusion of water, of blood, of grace, of words, and the like.
