What is the main function of lymph fluid?

1. Transport oxygen

2. Clear waste from the body

3. Regulate blood pressure

4. Provide nutrients to cells

The correct answer is: Clear waste from the body

The main function of lymph fluid is to clear waste from the body. Lymph fluid, which is part of the lymphatic system, plays a crucial role in maintaining fluid balance and immune function. It collects excess fluid that leaks from blood vessels into tissues, along with cellular waste products, pathogens, and other debris. This fluid is then filtered through lymph nodes, where immune cells can help eliminate harmful substances, before it eventually returns to the bloodstream. This waste-clearing function is vital for the body's overall health, as it aids in preventing the accumulation of toxins and supports immune responses to infections. The lymphatic system not only helps in waste removal but also in the absorption of fatty acids and fats from the digestive system, and in the transport of immune cells, further highlighting its importance in bodily functions.
