Cecum

The cecum or caecum (/ˈsiːkəm/, plural ceca /ˈsiːkə/; from the Latin caecus meaning blind) is an intraperitoneal pouch that is considered to be the beginning of the large intestine. It receives chyme from the ileum, and connects to the ascending colon of the large intestine. It is separated from the ileum by the ileocecal valve (ICV) or Bauhin's valve. It is also separated from the colon by the cecocolic junction. The appendix is connected to the cecum. While the cecum is usually intraperitoneal, the ascending colon is retroperitoneal.
