Final answer:
An Anastomosis refers to a surgical connection between blood vessels or the joining of one hollow or tubular organ to another, often ensuring a smooth blood flow even amid possible blockages.
Step-by-step explanation:
A surgical connection between blood vessels or the joining of one hollow or tubular organ to another is referred to as an Anastomosis. For instance, this term describes the area where vessels unite to allow blood to circulate even if there may be a partial blockage in another branch. Microscopically, an arteriovenous anastomosis is a short vessel connecting an arteriole directly to a venule and bypassing the capillary beds, thereby ensuring a continuous flow of blood.
