Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A
TRUE.
B
False.
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Undigested remains of food are passed through a one-way muscular valve into the first part of the large intestine known as the caecum – a small pouch that acts as a temporary storage site. By the time food remains have reached this point, about 5–12 hours have elapsed.

Detailed explanation-2: -After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. It takes about 36 hours for food to move through the entire colon.

Detailed explanation-3: -The cecum connects the small intestine to the colon. The colon includes the ascending colon, transverse colon, descending colon, and sigmoid colon. The sigmoid colon connects to the rectum and anal canal, which leads to the outside of the body.

Detailed explanation-4: -duodenum, the first part of the small intestine, which receives partially digested food from the stomach and begins the absorption of nutrients. The duodenum is the shortest segment of the intestine and is about 23 to 28 cm (9 to 11 inches) long.
