Quizplus · Accepted Answer

A) Esophagus - This is a hollow muscular tube that transports food and liquids from the throat to the stomach. It definitely contains a lumen.
B) Small intestine - This is a long, coiled hollow tube where most of the digestion and absorption of food takes place. It also has a lumen.
C) Stomach - The stomach is a muscular organ that stores food and begins the digestive process by secreting gastric juice. It has a large lumen.
D) Gall bladder - The gall bladder is a small organ that stores and concentrates bile, a digestive fluid produced by the liver. However, it is not typically considered a hollow organ in the same sense as the esophagus, stomach, or intestines because it does not have a continuous passage for substances to flow through it. Instead, it has a sac-like structure.
Therefore, the correct answer is:
D) Gall bladder - It is not considered a hollow organ in the same context as the esophagus, small intestine, and stomach.
