The fibrous sac surrounding the kidney is called the ________.
A) renal hilum
B) renal capsule
C) renal cortex

Accepted Answer

The renal capsule is a fibrous sac that surrounds the kidney and serves as a barrier against trauma and infection. The renal hilum is a notch on the medial side of the kidney where the renal artery, vein, and ureter enter and exit. The renal cortex is the outer layer of the kidney, while the adipose capsule is a layer of fat that surrounds the renal capsule and helps to protect the kidney. None of these descriptions match the definition of the fibrous sac surrounding the kidney, making B the best choice.
