Explanation:

Identify major retroperitoneal vessels

Using the Abdominal Anatomy knowledge point

• Q points to the abdominal aorta, which runs vertically on the left side of the vertebral column.
• C points to the inferior vena cava (IVC), situated to the right of the aorta.
• O points to the left renal vein, crossing anteriorly over the aorta to drain into the IVC.
• B points to the right renal vein, draining directly into the IVC.

Identify renal structures and vessels

Using the Abdominal Anatomy knowledge point

• P points to the left kidney.
• D points to the right renal artery, arising from the aorta and passing posterior to the IVC.
• E points to the right renal pelvis/ureter junction.
• F points to the right ureter, descending retroperitoneally.

Identify pelvic vessels and nerves

Using the Abdominal Anatomy knowledge point

• H points to the right common iliac artery, a terminal branch of the aorta.
• R points to the left common iliac vein, joining to form the IVC.
• S points to the left external iliac artery.
• G points to the right testicular/ovarian (gonadal) vein.
• I, J, K point to nerves of the lumbar plexus (e.g., ilioinguinal, lateral femoral cutaneous, femoral nerves).
• L and M point to internal iliac branches and pelvic structures.
• T points to the urinary bladder/uterus in the pelvic cavity.

Identify superior structures

Using the Abdominal Anatomy knowledge point

• A points to the diaphragm (specifically the right crus or dome).
• N points to the celiac trunk or superior mesenteric artery origin near the upper aorta.

Answer:

Based on the anatomical dissection of the posterior abdominal wall and pelvis, here is the identification of the labeled structures:

• A: Diaphragm
• B: Right renal vein
• C: Inferior vena cava
• D: Right renal artery
• E: Right renal pelvis
• F: Right ureter
• G: Right gonadal (testicular/ovarian) vein
• H: Right common iliac artery
• I: Ilioinguinal nerve
• J: Lateral femoral cutaneous nerve
• K: Femoral nerve
• L: Right external iliac artery
• M: Right internal iliac artery
• N: Celiac trunk / Superior mesenteric artery
• O: Left renal vein
• P: Left kidney
• Q: Abdominal aorta
• R: Left common iliac vein
• S: Left external iliac artery
• T: Urinary bladder (or uterus in this female pelvic section)
