B. Digestive system
C. Lymphatic system
Answer:
C. Lymphatic system
The lymphatic system is a critical component of the body's immune system and plays a vital role in maintaining fluid balance. This intricate network of organs and tissues helps to filter and collect the fluid that leaks from blood vessels before returning it to the bloodstream. The lymphatic system also functions to transport white blood cells, which are essential for fighting infections and diseases.
One of the key organs in the lymphatic system is the lymph nodes, which act as filtering stations that trap and eliminate harmful agents, such as bacteria and viruses, from the lymph fluid. The cleaned fluid is then transported back to the heart through the thoracic duct and the right lymphatic duct, eventually rejoining the bloodstream via the vena cava.
Without a properly functioning lymphatic system, the body would struggle to maintain its fluid balance and would be more susceptible to infections. Understanding the importance of this system can help us appreciate the intricacies of our body's natural defense mechanisms.
