B. It is divided into sections by capsular extensions called trabeculae.
C. Its white pulp consists of lymphatic cells.
D. It stores erythrocytes.
E. Its blood is supplied by the splenic artery and drained by the splenic vein.

Answer 1

The spleen is not involved in the production of lymphocytes like the lymph nodes and does not store erythrocytes. Its primary function is to filter blood and remove microbes and dying red blood cells.

Step-by-step explanation:

The spleen is an organ in the lymphatic system that acts as a filter for blood instead of lymph. It is not involved in the production of lymphocytes like the lymph nodes are. The spleen is responsible for removing microbes and other materials from the blood, including dying red blood cells. It also serves as the location of immune responses to blood-borne pathogens. The correct answer is D. It stores erythrocytes, as the spleen primarily filters blood instead of storing red blood cells.
