permeabilidad vascular
Nota de escopo: Propiedad del ENDOTELIO vascular capilar que permite el intercambio selectivo de sustancias entre la sangre y los tejidos vecinos y a través de barreras membranosas tales como la BARRERA ALVEOLO-CAPILAR, la BARRERA HEMATOACUOSA, la BARRERA HEMATOENCEFÁLICA, la BARRERA HEMATORRETINIANA y la BARRERA HEMATOTESTICULAR. Las pequeñas moléculas liposolubles, como el dióxido de carbono y el oxígeno, se mueven libremente por difusión. El agua y las moléculas hidrosolubles no pueden pasar a través de la pared endotelial, por lo que están a expensas de poros microscópicos. Dichos poros muestran áreas estrechas (UNIONES ESTRECHAS) que pueden limitar los movimientos de moléculas grandes.

Nota de escopo: The property of blood capillary ENDOTHELIUM that allows for the selective exchange of substances between the blood and surrounding tissues and through membranous barriers such as the BLOOD-AIR BARRIER; BLOOD-AQUEOUS BARRIER; BLOOD-BRAIN BARRIER; BLOOD-NERVE BARRIER; BLOOD-RETINAL BARRIER; and BLOOD-TESTIS BARRIER. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (TIGHT JUNCTIONS) which may limit large molecule movement.
