Final answer:
The lymphatic system is a network of vessels, cells, and organs that collect excess fluids from the body tissues and return it to the circulatory system. It is closely associated with the immune system and helps filter pathogens from the blood. Lymphatic vessels carry lymph, a fluid that leaks out of capillaries and contains white blood cells, back into the bloodstream.
Step-by-step explanation:
The lymphatic system is a network of vessels, cells, and organs that collects excess fluids from the body tissues and returns it to the circulatory system. It is also closely associated with the immune system and helps filter pathogens from the blood. Lymphatic vessels carry lymph, a fluid that leaks out of capillaries and contains protective white blood cells, back into the bloodstream. Lymph nodes, located along the lymphatic vessels, filter out pathogens and destroy them.
