Final answer:
The space behind the stomach and in front of the retroperitoneal organs like the pancreas is known as the lesser sac or omental bursa.
Step-by-step explanation:
The space you're referring to behind the stomach but in front of the retroperitoneal organs, such as the pancreas, is commonly referred to as the lesser sac or omental bursa. This space in the human anatomy is situated posterior to the stomach and the greater omentum, and anterior to the retroperitoneal organs.
In detail, the pancreas is a glandular organ with both endocrine and exocrine functions. It is located in the upper left abdomen behind the stomach. The pancreas is approximately 15 centimeters (6 inches) long and has a flat, oblong shape. It is divided into a head, which is nestled into the 'c-shaped' curvature of the duodenum, a body that extends horizontally across the abdomen, and a tail that ends near the spleen. The gland secretes digestive enzymes into the duodenum through its major ducts and releases hormones like insulin and glucagon directly into the blood.
