crystalloid

 [kris´tah-loid]
1. resembling a crystal.
2. a substance whose particles are smaller than those of a colloid, form a true solution, and are therefore capable of passing through a semipermeable membrane, as in dialysis. The physical opposite of a crystalloid is a colloid, which does not dissolve and does not form true solutions.

crys·tal·loid

(kris'tăl-oyd),
1. Resembling a crystal, or being such.
2. A body that in solution can pass through a semipermeable membrane, as distinguished from a colloid, which cannot do so.
3. A hydration solution that contains only electrolytes.

crystalloid

[kris′təloid]
Etymology: Gk, krystallos + eidos, form
a substance in a solution that can diffuse through a semipermeable membrane. Compare colloid.

crystalloid

1. resembling a crystal.
2. a noncolloid substance. Crystalloids form true solutions and therefore are capable of passing through a semipermeable membrane, as in dialysis. The physical opposite of a crystalloid is a colloid (3), which does not dissolve and does not form true solutions.

crystalloid particle
a matrix particle in a single membrane contained in a peroxisome, when viewed through an electron microscope. Called also nucleoid.
crystalloid solution
contains electrolytes and nonelectrolytes which will diffuse into all body fluid compartments. Examples are Ringer's solution and 5% dextrose in water.
