Final answer:
The combining form 'pancreato/o' refers to the pancreas, an organ with both exocrine and endocrine functions, located behind the stomach and extending towards the spleen.
Step-by-step explanation:
The combining form pancreato/o indicates the pancreas, which is an essential organ within the human body performing both exocrine and endocrine functions. The pancreas is a long, slender glandular organ situated between the stomach and the proximal portion of the small intestine. It secretes digestive enzymes through exocrine cells and hormones such as insulin and glucagon through endocrine cells, making it a heterocrine gland. Its location is transverse in the retroperitoneum, lying behind the stomach. The pancreas extends with its head nestled into the 'c-shaped' curvature of the duodenum, and its body and tail reaching towards the spleen.
