semipermeable

 [sem″e-per´me-ah-bl]
permitting passage only of certain molecules.

sem·i·per·me·a·ble

(sem'ē-per'mē-ă-bĕl),
Freely permeable to water (or other solvent) but relatively impermeable to solutes. Depending on the context, it has been used to imply impermeability to all solutes except very small uncharged molecules (for example, a cell membrane), or merely impermeability to very large molecules such as proteins (for example, a capillary membrane).

semipermeable

/semi·per·me·a·ble/ (sem″e-per´me-ah-b'l) permitting passage only of certain molecules.

semipermeable

(sĕm′ē-pûr′mē-ə-bəl, sĕm′ī-)
adj.
1. Partially permeable.
2. Allowing passage of certain, especially small, molecules or ions but acting as a barrier to others. Used of biological and synthetic membranes.

semipermeable

[-pur′mē·əbəl]
Etymology: L, semi, half, permeare, to pass through
pertaining to a membrane that allows the passage of some molecules but prevents the passage of others. Also selectively permeable.

semipermeable

Able to allow the passage of molecules below a certain size and to retain those above this size. Much of PHYSIOLOGY depends on the semipermeability of body membranes.

semipermeable

membrane permeable to water, ions and small molecules, but normally impermeable to larger molecules/colloids, e.g. tunica intima
