Which system is essential for cleansing the blood and housing white blood cells?

The lymphatic system is crucial for cleansing the blood and supporting the immune system by housing white blood cells. This network of vessels and tissues helps remove waste products, excess fluids, and toxins from the body, and it plays a significant role in maintaining fluid balance. The lymphatic system transports lymph, a fluid that contains white blood cells, particularly lymphocytes, which are responsible for targeting and eliminating pathogens and infections. This system also facilitates the absorption of fats and fat-soluble vitamins from the digestive system. Therefore, the lymphatic system is essential for both cleansing the blood and providing a location for immune functions to occur seamlessly.

In contrast, the nervous system is primarily responsible for transmitting signals and regulating activities throughout the body; the muscular system focuses on movement and body stability; and the respiratory system facilitates gas exchange, playing a different role in overall bodily functions.
