Which term describes inadequate venous return due to vein blockage or valve leakage?

• A. Colitis
• B. Chronic Venous Insufficiency
• C. Enteritis
• D. Diurectic

Answer: (B)

Inadequate venous return from the legs is described by chronic venous insufficiency, a condition where the veins can’t push blood back toward the heart because the valves fail to close properly or there’s an obstruction. The one‑way valves normally prevent backflow; when they become incompetent or a blockage exists, blood pools in the legs, leading to swelling, skin changes, and sometimes venous ulcers. This differs from colitis (inflammation of the colon) or enteritis (inflammation of the intestines), which are digestive tract conditions and not about venous return. A diuretic is a medication that increases urine production to reduce fluid buildup, not a description of a venous return problem.
