Understand the role of the spleen in the lymphatic system. The spleen is an organ located in the upper left part of the abdomen, and it plays a crucial role in filtering blood and managing the immune response.
Identify the primary functions of the spleen. The spleen is responsible for filtering blood, removing old or damaged red blood cells, and storing white blood cells and platelets.
Consider the options provided in the problem. The options include filtering blood and removing old or damaged red blood cells, maturing B-lymphocytes, producing T-lymphocytes, and draining excess interstitial fluid.
Evaluate each option based on the known functions of the spleen. Filtering blood and removing old or damaged red blood cells is a well-documented primary function of the spleen.
Conclude that the primary function of the spleen in the lymphatic system, based on the options given, is filtering blood and removing old or damaged red blood cells.
