Which lymphatic organ is located in the left upper quadrant (LUQ) of the abdomen?
A
Tonsil
B
Appendix
C
Thymus
D
Spleen
Verified step by step guidance1
Step 1: Begin by identifying the anatomical location of the left upper quadrant (LUQ) of the abdomen. The LUQ is located on the left side of the body, above the umbilical region, and includes organs such as the stomach, spleen, and part of the pancreas.
Step 2: Review the function and location of each lymphatic organ listed in the options: Tonsil, Appendix, Thymus, and Spleen.
Step 3: Recall that the tonsils are lymphatic tissues located in the pharyngeal region (throat area), not in the abdomen.
Step 4: Understand that the appendix is a small lymphatic organ located in the lower right quadrant (LRQ) of the abdomen, not the LUQ.
Step 5: Note that the thymus is located in the mediastinum (chest area) and is not part of the abdominal cavity. The spleen, however, is a lymphatic organ located in the LUQ of the abdomen, making it the correct answer.
