Which term is defined as 'The connecting channel of organs of the gastrointestinal tract'?

• A. Alimentary canal
• B. Bolus
• C. Esophagus
• D. Sigmoidoscopy

Answer: (A)

Identifying the term for the continuous passage through which digestion occurs helps you connect anatomy with function. The connecting channel of organs of the gastrointestinal tract is the alimentary canal, a tube that runs from the mouth to the anus and includes the mouth, esophagus, stomach, and intestines. It’s the pathway where food is ingested, broken down, nutrients absorbed, and waste formed. Bolus is the chewed mass of food before swallowing, the esophagus is the tube that transports that material, and sigmoidoscopy is a procedure to view part of the large intestine. So, the term that best fits the definition is alimentary canal.
