Which of the following is NOT a function of the spleen?

1. Filtration of blood

2. Production of digestive enzymes

3. Storage of blood cells

4. Destruction of old blood cells

The correct answer is: Production of digestive enzymes

The spleen plays multiple essential roles in the body, particularly in the immune and circulatory systems. One of its primary functions is the filtration of blood, where it removes debris and pathogens, and it also has an important role in the destruction of old or damaged blood cells, especially red blood cells. Additionally, the spleen acts as a reservoir for blood, storing blood cells and platelets that can be released when needed. The function of producing digestive enzymes is not associated with the spleen. This role is primarily fulfilled by the pancreas and various organs within the digestive system. Therefore, the correct answer identifies that the spleen does not produce digestive enzymes, distinguishing it from the other valuable functions it performs related to blood and immune system maintenance. Understanding the specific functions of each organ highlights the specialization within the body's systems and clarifies that the spleen does not participate in digestive processes.
