Definition
English
:
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.
