Large intestine consist of
1- cecum
2-colon
3-rectum
The cecum open into colon .Colon devided into
1-ascending
2-transerve
3-descending
4-sigmoid colon
There are some bacteria in small intestine which produce some vitamins which are very essential for us .The most important of these is Vitamin K and BIOTIN(a B vitamin)
CECUM,which is the proximal end of large intestine , is where the large and small intestine meet. The cecum extends inferiourly about 6cm behind the ileocecal junction in the form of a blind sac. Attached to the inferior surface of the cecum is a small blind tube about 9 cm long called VERMIFORM APPENDIX. The wall of appendix contain many lymph nodes
RECTUM is a straight, muscular tube that begins at the termination of the sigmoid colon and ends at the anal canal
The last 2-3 cm of the digestive tract is the anal ANAL CANAL .  It begins at the inferior of the rectum and ends at the anus(external GI tract opening). The smooth muscel layer and skeletal muscel  form the sphincter of the anal canal
Many people thinks that maximum absorption of water occur in the large intestine but it's not correct. Maximum water absorption occur in small intestine. In large intestine the substance which absorbs maximum is water.

APPENDICITIS is the inflammation of vermiform appendix
APPENDECTOMY is removal of appendix
