Final answer:
The liver and gallbladder are the organs unique to the right upper quadrant, with the liver being a major digestive gland and the gallbladder storing and concentrating bile.
Step-by-step explanation:
The organs unique to the right upper quadrant include the liver and the gallbladder. The liver is the largest gland in the body and plays a critical role in metabolism, digestion, and regulation, and is protected by the ribs as it lies just below the diaphragm. It is divided into several lobes, with the right lobe being significantly larger than the left.
The gallbladder is another organ located in the right upper quadrant, nestled on the posterior aspect of the liver. This small muscular sac stores and concentrates bile, releasing it into the duodenum when needed. An important part of the biliary system, it has three distinct regions: the fundus, the body, and the neck.
