Which of the following is a muscular tube that runs from the mouth to the anus?

The alimentary canal, also known as the gastrointestinal tract, is a muscular tube that connects the mouth to the anus and is in charge of food digestion and absorption. The mouth, pharynx, oesophagus, stomach, small intestine, large intestine, rectum, and anus are all part of it.

The alimentary canal includes the mouth, oesophagus, and anus, but the entire canal is responsible for the movement and processing of ingested food.

The small intestine is a section of the alimentary canal located between the stomach and the large intestine that absorbs the majority of nutrients.

The alimentary canal is an important part of the digestive system because it ensures that food is broken down and processed so that the body can extract nutrients and energy for vital functions.
