What is the primary hematopoietic function of the spleen?

Question

Quizplus · Accepted Answer

The primary hematopoietic function of the spleen is culling and pitting, which involves the removal of old or damaged red blood cells and platelets from circulation. This function does not involve the production of new blood cells, which is known as hematopoiesis. The spleen also plays a role in lymphatic drainage and immune function but these are not its primary hematopoietic functions. T cell maturation primarily occurs in the thymus. Extramedullary hematopoiesis can occur in the spleen in response to certain conditions, but it is not the primary function.
