For 10 points—name these eight-to-ten- micron-diameter conduits lined by a single layer of endothelium which carry blood from the arterioles to the tissues.
Their walls, which can be characterized as tight, continuous, discontinuous, or fenestrated depending on porosity, facilitate the exchange of cells, chemicals, and nutrients.
