What is the primary function of the spleen?

Digestive aid
Blood filtration
Nutrient absorption
To regulate blood sugar

The correct answer is: Blood filtration

The primary function of the spleen is blood filtration. The spleen plays a crucial role in the immune system and helps filter out older or damaged red blood cells from circulation. It also serves to remove pathogens and debris from the blood, thus contributing significantly to the body’s immune defense. Additionally, the spleen recycles iron from the hemoglobin of aged red blood cells for the production of new cells. While options regarding digestive aid, nutrient absorption, and regulation of blood sugar relate to other organ systems, they do not encompass the main role of the spleen, which is specifically oriented toward maintaining healthy blood and immune function.
