Question

multiple choice question
which type of anastomosis provides several alternative routes of drainage from an organ?
arterial
venous
arteriovenous

Explanation:

To determine the correct answer, we analyze the function of each anastomosis type:

• Arterial anastomosis: Primarily focuses on blood supply (delivery), not drainage.
• Venous anastomosis: Involves veins, which are responsible for draining blood from organs. Having multiple venous anastomoses creates alternative drainage routes to ensure blood can exit an organ even if one path is obstructed.
• Arteriovenous anastomosis: Connects arteries and veins directly, mainly for regulating blood flow (e.g., thermoregulation) rather than providing drainage routes from an organ.

So, venous anastomosis is the type that provides several alternative routes of drainage from an organ.

Answer:

B. Venous
