Final answer:
The B. kidney is not included in the blocks of the digestive system, as it is part of the urinary system. The appendix, gallbladder, and esophagus are parts of the digestive system, with the gallbladder being an accessory organ and the esophagus part of the upper GI tract.
Step-by-step explanation:
The organ that is not included in the blocks of the digestive system is the kidney. The digestive system consists of the gastrointestinal (GI) tract, which includes the mouth, esophagus, stomach, small intestine, and large intestine. Additionally, there are accessory organs such as the liver, gallbladder, and pancreas, that are involved in digestion but not part of the GI tract. The appendix is a part of the large intestine (attached to the cecum), while the gallbladder is an accessory organ that stores bile, and the esophagus is part of the upper GI tract. The kidneys are part of the urinary system, which is separate from the digestive system.
- Appendix - part of the large intestine
- Kidney - not part of the digestive system
- Gallbladder - accessory organ of the digestive system
- Esophagus - part of the upper GI tract
