An arterio-venous anastomoses makes a direct connection between which tissue?

An arterio-venous anastomosis is a direct connection between an artery and a vein. The term itself specifies the vessels involved, creating a high-flow pathway that bypasses the capillary bed, so arterial blood flows straight into the venous system. This kind of shunt is exemplified by AV fistulas used for long-term dialysis access. It’s not a connection between nerves and veins or between arteries and lymphatic vessels, and while you could describe the junction as vein-to-artery, the standard terminology emphasizes artery-to-vein.
