A direct connection between an arteriole and a venule without an intervening capillary bed is a/an ________.
A) venous sinus
B) arteriovenous anastomosis
C) metarteriole
D) arterial capillary
Arteriovenous Anastomosis
Vessel through which blood is shunted from an arteriole to a venule without passing through the capillaries.
Arteriole
A small artery that leads into capillaries, controlling blood flow and pressure by the contraction and relaxation of its muscular wall.
Venule
Small blood vessels that allow deoxygenated blood to return from capillary beds to larger blood vessels called veins.

Final Answer :
B
Explanation :
An arteriovenous anastomosis is a direct connection between an arteriole and a venule, bypassing the capillary bed. This allows for the regulation of blood flow, either bypassing the capillaries when not needed or allowing blood to flow through them when required.
