Caecums

caecum cae"cum, n.; pl. {C[ae]cums}, L. {C[ae]ca}. [L. caecus blind, invisible, concealed.] (Anat.) (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}. [Also spelled {cecum}.] [1913 Webster]

Note: The c[ae]cum 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 c[ae]ca. [1913 Webster]
