Final answer:
The pancreas is located in the upper left abdomen and spans multiple abdominopelvic regions, specifically the epigastric, left hypochondriac, and umbilical regions.
Step-by-step explanation:
The pancreas is a versatile organ with both exocrine and endocrine functions, located in the upper left abdomen behind the stomach. Given the regions of the pancreas, it spans multiple abdominopelvic regions: primarily the epigastric region, where the head of the pancreas is nestled into the C-shaped curvature of the duodenum, and extending to the left to reach the left hypochondriac region, where the tail of the pancreas is in proximity to the spleen. Furthermore, part of its body extends horizontally, likely brushing the upper regions of the umbilical region. Hence, all three options a) Epigastric, b) Left Hypochondriac (tail), c) Umbilical are correct when describing the location of the pancreas.
