Which organ is surrounded by Glisson's capsule?

Glisson's capsule is a thin layer of connective tissue that surrounds the liver. This fibrous layer plays a crucial role in maintaining the structural integrity of the liver and provides protection to its underlying parenchyma. The capsule also contains blood vessels, lymphatics, and nerves that serve the liver, highlighting its importance in both support and function.

In the context of the other options, while the spleen, kidney, and stomach each have protective layers or capsules, they are not specifically surrounded by Glisson's capsule. For instance, the spleen is covered by a fibrous capsule but this structure is distinct from Glisson's capsule. Similarly, the kidneys are covered by a renal fascia, and the stomach has a serosal layer, but neither of these is synonymous with Glisson's capsule. The liver's unique association with Glisson's capsule is a distinguishing factor that confirms its role as the correct answer. This anatomical association is essential for understanding liver anatomy and function in medical sonography.
