Detailed explanation-1: -The esophagus is a 25-cm long muscular tube that connects the pharynx to the stomach. The length of the esophagus at birth varies between 8 and 10 cm and measures about 19 cm at age 15 years.
Detailed explanation-2: -The statement “The esophagus is digestive in function” is true. The esophagus is a muscular hollow tube that connects the mouth to the stomach, making it the second major organ in the digestive system if ordering by function.
Detailed explanation-3: -The oesophagus (gullet), around 25cm in length, connects the mouth to the stomach via the pharynx (Fig 4). The oesophagus does not produce digestive enzymes, but it does secrete large amounts of mucus that act as a lubricant, ensuring the smooth transit of the food bolus.
