The cecum marks the beginning of the large intestine and is basically a big pouch that receives waste material from the small intestine.

Cecum
The cecum is about six centimeters (cm) long and 7.5 cm wide. The ileum (of the small intestine) dumps waste material into the cecum and the cecum passes it on to the colon, specifically the ascending colon. It doesn't do so through a little tube; the cecum is continuous with the colon.
