permeability

[pur′mē·əbil′itē]
Etymology: L, permeare, to pass through
the degree to which one substance allows another substance to pass through it. See also capillary permeability, magnetic permeability, osmosis. permeable, adj.

permeability

passage of substances through a membrane
  • increased vascular permeability capillary state in acute inflammation; larger gaps appear between tunica intima cells, permitting passage of large molecules (e.g. plasma proteins) and cells (e.g. neutrophils, macrophages, fibroblasts, platelets and sometimes erythrocytes) from the capillary into the tissue spaces

  • vascular permeability passage of small molecules (e.g. water, oxygen, carbon dioxide and glucose) into and out of the capillary; normal state, permitting tissue respiration

per·me·a·bil·i·ty

(pĕr'mē-ă-bil'i-tē)
The property of being penetrable.

permeability (pur´mēəbil´itē),
