What is the main role of the lymphatic system?

1. Transport oxygen

2. Remove waste and toxins

3. Regulate body temperature

4. Support muscle function

The correct answer is: Remove waste and toxins

The main role of the lymphatic system is to remove waste and toxins from the body. The lymphatic system is integral to the body's immune system, as it helps to transport lymph, a fluid that contains infection-fighting white blood cells, throughout the body. By filtering lymph through lymph nodes, which trap pathogens and foreign particles, the lymphatic system plays a crucial role in maintaining the body's fluid balance as well as defending against disease. In addition to waste removal, the lymphatic system also absorbs fats and fat-soluble nutrients from the digestive system and transports them to the bloodstream. This dual role of waste removal and nutrient transport illustrates the system's significance in overall health and homeostasis. The effectiveness of the lymphatic system in cleansing the body of toxins is essential for preventing infections and maintaining the health of body tissues.
