The Spigelian lobes are two narrow triangular structures located between the gallbladder and duodenum. The name comes from the name of the Dutch anatomist and botanist A. Spigelius van der Speigel (1579-1619).
Spigelian lobes are important for human health. The gallbladder, which is of key importance in digestion, is located in them. When the gallbladder or its functioning is impaired, a variety of gastrointestinal conditions can occur, including indigestion, bowel disorders, and liver inflammation.
The functions of the Spigelian lobes are also important for metabolism and immunity. Carbon dioxide, a product of chemical reactions in the intestines, is absorbed through the liver into the blood and then converted into carbon dioxide by the lungs
