Verified step by step guidance

Understand the role of the lymphatic system: The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste, and other unwanted materials. Its primary function is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.

Identify the primary lymphatic organs: The main lymphatic organs include the lymph nodes, spleen, thymus, and tonsils. These organs are involved in the production and maturation of lymphocytes, which are crucial for the immune response.

Differentiate between lymphatic and non-lymphatic organs: The pancreas, gallbladder, and liver are not part of the lymphatic system. The pancreas is involved in digestion and blood sugar regulation, the gallbladder stores bile, and the liver has multiple functions including detoxification and protein synthesis.

Recognize the spleen's function: The spleen is a lymphatic organ that filters blood, recycles old red blood cells, and helps fight certain kinds of bacteria. It plays a crucial role in the immune system by producing lymphocytes and storing white blood cells and platelets.

Conclude by identifying the correct lymphatic organ: Based on the functions and roles of the organs listed, the spleen is the correct answer as it is the only lymphatic organ among the options provided.
