The correct answer to this question is renal fascia. It is also known as the Gerota's fascia and Gerota's capsule. It is apart of the urinary system. Not only does it connect the kidney and adrenal glands, but it also seperates pararenal fat from the adipose capsule of the kidney. The order of the deeper layers of the renal fascia are the adipose capsule, the renal capsule, and the parenchyma.
The kidney also has spaces which are divded into three compartments. These compartments include the anterior, perinephric, and posterior pararenal spaces. The renal fascia has involvement in many urinary tract diseases, which include renal calculi, focal renal scarring, and acute renal infection.
