Question

why do vermiform appendix is called 'a blind sac' ?

Answer 1

vermiform appendix is called as 'blind sac' becauseThe vermiform appendage—in which some recent medical writers have vainly endeavoured to find a utility—is the shrunken remainder of a large and normal intestine of a remote ancestor. This interpretation of it would stand even if it were found to have a certain use in the human body. Vestigial organs are sometimes pressed into a secondary use when their original function has been lost."
