The flow of lymph is maintained by__________?
Correct answer: D. All of these
- A. Movement of viscera
- B. Breathing movements
- C. Valves
- D. All of these
Explanation
Lymph is moved by skeletal-muscle and visceral movements and by pressure changes during breathing, while valves prevent its backward flow; together these mechanisms maintain one-way lymph movement. Students may choose valves alone, but valves do not actively propel lymph and mainly stop backflow.

About Lymphatic System
The lymphatic system returns excess tissue fluid to the bloodstream and supports immune defence through lymph, lymph vessels, lymph nodes, the spleen, thymus and tonsils. It also transports absorbed fats from intestinal lacteals, which distinguishes lymphatic circulation from the blood vascular system.
