Verified step by step guidance

Understand the primary functions of the spleen in the human body. The spleen is an organ involved in the lymphatic system and plays a crucial role in filtering blood.

Recognize that the spleen is responsible for removing old or damaged red blood cells from circulation. This is a key function that helps maintain healthy blood cell levels.

Differentiate the spleen's functions from those of other organs. For example, the liver stores bile, and the pancreas produces insulin and secretes digestive enzymes.

Identify that the spleen also helps in the immune response by producing white blood cells and storing platelets, but its main role in this context is filtering blood.

Conclude that the correct function of the spleen, as given in the options, is filtering blood and removing old red blood cells, distinguishing it from the functions of other organs mentioned.
