vessels, blood, visualization of,

n the methods by which the blood vessels are seen by the examiner. Direct visualization of blood vessels is possible only to a limited extent. The blood vessels in the retina can be directly visualized; the capillary loops in the fingernail can be seen by microscopy, and the blood vessels in the oral mucosa and gingivae can be visualized by infrared photography. More recently, radiography and cineradiography are used to visualize radiopaque substances. These methods can reveal the actual blood column, its width, variation in contour, and pathway. Arteriograms and venograms are useful in revealing spasms, obstructions, congenital defects, and collateral circulation of the deeper tissues.

vessels, efferent,

n.pl vessels that carry fluids such as lymph or blood away from a body part.
