Which of the following is a function of the lymphatic system?

A. The thymus gland is involved in the maturation of T-cells, a type of white blood cell, but it does not remove worn-out blood cells or serve as a blood reservoir.
B. The liver has various functions, including detoxification, protein synthesis, and storage of glycogen, but it is not the primary organ for removing worn-out blood cells or serving as a blood reservoir.
C. The spleen is a large lymphatic organ that filters blood, removes worn-out blood cells, and serves as a reservoir for blood. It also plays a role in immune function by filtering pathogens from the blood.
D. Interstitial spaces refer to the fluid-filled spaces between cells in tissues and are not an organ involved in blood cell removal or storage.

A. The inguinal lymph nodes are not part of the hepatic portal system. The hepatic portal system refers to the venous system that directs blood from the digestive organs to the liver, while the inguinal lymph nodes are involved in immune function.
B. The inguinal lymph nodes do not line the entrance of the spleen. The spleen is located in the upper left abdomen and has its own set of immune cells but does not directly connect to the inguinal lymph nodes.
C. The inguinal lymph nodes are located in the groin area. They are part of the body's lymphatic system and help filter lymph fluid from the lower extremities and genital region.
D. Kupffer cells are specialized macrophages found in the liver, not in the inguinal lymph nodes. These cells are involved in the filtration of blood and the removal of pathogens and debris.
