What is the primary function of the lymphatic system?

• A. Helps support the immune systems
• B. Removes waste from the blood
• C. Connects bones at joints
• D. Aids in muscle activation

Answer: (A)

The primary function of the lymphatic system is to help support the immune system. This system plays a crucial role in the body's defense mechanism by facilitating the transport of lymph, a fluid that contains immune cells such as lymphocytes. When tissues are infected or inflamed, lymphatic vessels help to collect and transport the lymph containing pathogens and cellular debris to lymph nodes, where immune responses are activated. Within the lymph nodes, immune cells can identify and respond to the presence of pathogens, leading to the production of antibodies and other immune responses that protect the body from infections and diseases.

While other systems or structures might contribute to the functions mentioned in the other choices, they do not pertain to the primary role of the lymphatic system. This underscores the essential connection between the lymphatic system and immune function, making it a fundamental component of the body’s defense against disease.
