What does "caecum" mean?

Caecum: (a) A cavity open at one end, as the blind end of a canal or duct. (b) The blind part of the large intestine beyond the entrance of the small intestine; -- called also the blind gut. Note: The cæcum is comparatively small in man, and ends in a slender portion, the vermiform appendix; but in herbivorous mammals it is often as large as the rest of the large intestine. In fishes there are often numerous intestinal cæca.
