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. It is part of the immune system.

Identify the organs of the lymphatic system: The primary lymphatic organs include the tonsils, thymus, spleen, and lymph nodes.

Evaluate the size and function of each organ: The tonsils are small masses of lymphoid tissue located at the back of the throat. The thymus is a small organ located in the upper chest. Lymph nodes are small, bean-shaped structures scattered throughout the body.

Focus on the spleen: The spleen is located in the upper left part of the abdomen, just beneath the rib cage. It is the largest organ in the lymphatic system and plays a crucial role in filtering blood, recycling old red blood cells, and storing white blood cells and platelets.

Conclude with the correct answer: Based on the size and function, the spleen is the largest lymphatic organ in the body.
