Final answer:

The blind sac at the beginning of the large intestine is called the cecum, and it is followed by the ascending colon and colic flexure. The appendix is a coiled tube that attaches to the cecum and may have a role in bacterial repopulation.

Step-by-step explanation:

The initial or first region of the large intestine is called the cecum. It is a sac-like structure that receives the contents of the ileum and continues the absorption of water and salts. The appendix is a coiled tube that attaches to the cecum. Although the appendix is generally considered vestigial, it may serve as a bacterial reservoir in cases of diarrheal illness. The ascending colon and colic flexure are other regions of the large intestine, but they are not the blind sac at the beginning of the large intestine.
