Glisson's capsule: The capsule of the liver. A layer of connective tissue surrounding the liver and ensheathing the hepatic artery, portal vein, and bile ducts within the liver.
Renal capsule: The renal capsule is a tough fibrous layer surrounding the kidney and covered in a layer of perirenal fat known as the adipose capsule of kidney. Adipose capsule is sometimes included in structure of renal capsule.

Glisson's Capsule and Renal Capsule: Differences

Glisson's capsule and renal capsule are two distinct structures present in the human body. Both of these capsules have different functions and are present in different parts of the body. Here are some of the key differences between Glisson's capsule and renal capsule:

Location
- Glisson's capsule is located in the liver, surrounding the hepatic parenchyma.
- Renal capsule is located in the kidney, surrounding the renal parenchyma.

Structure
- Glisson's capsule is a thin, fibrous layer that surrounds the liver and is continuous with the connective tissue of the liver.
- Renal capsule is a tough, fibrous layer that surrounds the kidney and is made up of collagen fibers.

Function
- Glisson's capsule is responsible for protecting the liver and providing structural support to the hepatic parenchyma.
- Renal capsule is responsible for protecting the kidney and maintaining the shape of the renal parenchyma.

Composition
- Glisson's capsule is composed of collagen fibers, elastic fibers, and smooth muscle cells.
- Renal capsule is composed of collagen fibers and fibroblasts.

Importance
- Glisson's capsule is important in liver surgery as it helps to prevent bleeding and damage to the liver.
- Renal capsule is important in kidney surgery as it helps to prevent damage to the kidney and surrounding structures.

In conclusion, Glisson's capsule and renal capsule are two separate structures that have different locations, structures, functions, compositions, and importance. Understanding these differences is important for medical professionals to properly diagnose and treat conditions related to the liver and kidney.
