What role does the adipose capsule play in relation to the kidneys?

1. Protects and stabilizes the kidneys

2. Stores excess urine

3. Filters out harmful substances

4. Controls fluid balance

The correct answer is: Protects and stabilizes the kidneys

The adipose capsule, also known as perirenal fat, plays a crucial role in protecting and stabilizing the kidneys. This layer of fat surrounds the kidneys and serves as a cushion, providing physical protection from trauma and external impacts. Additionally, the adipose capsule helps to anchor the kidneys in place within the abdominal cavity, preventing excessive movement that could affect kidney function. The roles of the other options, such as storing urine or filtering out harmful substances, are functions associated with different structures in the urinary system. The kidneys themselves filter blood and produce urine, while aspects like fluid balance are regulated by hormonal mechanisms involving the kidneys rather than being a direct function associated with the adipose capsule.
