The difference between pancreas and spleen

Pancreas and spleen are important organs located in the upper part of human abdominal cavity Although there are similarities, the functions, structures and appearances of the two organs are quite different The pancreas produces enzymes and hormones that help digest and regulate blood sugar It's a rectangle, made up of two clusters of cells called drupes and islets of Langerhans As a part of the lymphatic system, the spleen is mainly composed of red pulp and white pulp The shape of the spleen is like a bean The main difference between pancreas and spleen is function The main function of the pancreas is to produce glucagon, insulin, somatostatin and other hormones, as well as digestive enzymes These pancreatic hormones play an important role in regulating blood glucose level Enzymes produced by the pancreas are sent to the small intestine and bile ducts, where they help digest by breaking down carbohydrates, acids, proteins, fats and counteracting stomach acid Despite its proximity to the pancreas, the spleen works quite differently This abdominal organ is part of the lymphatic system that regulates fluid balance and helps fight infection It also helps to filter the waste in the blood, dispatch nearby white blood cells, destroy blood viruses and other invasive foreign bodies The appearance and structure of pancreas and spleen are also very different The length of pancreas is about 15.25 cm, which is a rectangle with a narrow upper part Most of them are composed of two kinds of cell clusters: small drupe and islet These small nuclear clusters secrete pancreatic enzymes, and the islets produce pancreatic hormones On the other hand, the spleen is shaped like a bean, about 10.15 cm long It is mainly composed of red pulp and white pulp The function of red pulp is to remove the garbage in the blood, while white pulp produces and dispatches white blood cells, and checks and destroys the foreign bodies that invade the blood, such as viruses.
