Which of the following are parts of the digestive system but do not constitute the alimentary canal?

The digestive system is responsible for breaking down food into nutrients that the body can absorb and use. The alimentary canal, which is a muscular tube that extends from the mouth to the anus, is the primary component of the digestive system. It includes the mouth, oesophagus, stomach, small intestine, large intestine, rectum, and anus.

However, there are other organs that play important roles in digestion but are not part of the alimentary canal. These include the liver and pancreas.

The liver is a large organ located in the upper right portion of the abdomen. It produces bile, a fluid that helps in the digestion of fats. The pancreas, on the other hand, is an organ located beneath the stomach that produces digestive enzymes and hormones that help regulate blood sugar levels and aid in food digestion.
