A) liver
B) spleen
C) thymus
D) tonsils

Accepted Answer

The liver is not part of the lymphatic system. It is a large, complex organ in the upper right quadrant of the abdomen that performs many functions, such as filtering toxins from the blood and producing bile to aid in digestion. The other options (spleen, thymus, and tonsils) are all part of the lymphatic system and play important roles in immune function.
