Final answer:
The statement that the Right Upper Quadrant contains the major portion of the liver and the gallbladder is True. The liver, being the largest gland, resides mainly in the RUQ with the gallbladder positioned beneath it.
Step-by-step explanation:
The Right Upper Quadrant (RUQ) of the abdominal cavity indeed contains the major portion of the liver and the gallbladder, making the statement True. The liver, the largest gland in the body, has two primary lobes, with the larger right lobe occupying space in the RUQ. The gallbladder, a small pouch-like organ, is nested beneath the right lobe of the liver. It is responsible for storing and concentrating bile produced by the liver.
The liver's vital role extends beyond digestion as it is also fundamental in metabolism and regulation. It is located just below the diaphragm and receives protection from the surrounding ribs. Meanwhile, the gallbladder stores bile that is later released into the duodenum to aid in the digestion of lipids.
