Detailed explanation-1: -Thus, the pathway of digestion begins in the mouth, followed by the esophagus, stomach, small intestine, large intestine, and anus. Hence, the incorrect answer is option (b) food enters the large intestine before the small intestine.
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 correct statement is “large intestine is shorter and wider than the small intestine of the human alimentary canal".
Detailed explanation-4: -Major absorption of glucose and amino acid occurs in the small intestine and not in large intestine.
Detailed explanation-5: -The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place in the small intestine.
