A fluid substance; a body whose particles move easily among
themselves.

Note: Fluid is a generic term, including liquids and gases as
species. Water, air, and steam are fluids. By analogy,
the term was sometimes applied to electricity and
magnetism, as in phrases electric fluid, magnetic
fluid, though not strictly appropriate; such usage has
disappeared.

Fluids of the body. (Physiol.) The circulating blood and
lymph, the chyle, the gastric, pancreatic, and intestinal
juices, the saliva, bile, urine, aqueous humor, and muscle
serum are the more important fluids of the body. The
tissues themselves contain a large amount of combined
water, so much, that an entire human body dried in vacuo
with a very moderate degree of heat gives about 66 per
cent of water.
