4. 肾的被膜
纤维囊(Fibrous capsule)
－a strong fibrous capsule which strips easily from a normal kidney surface but adheres firmly to an organ that has been inflamed.
脂肪囊(Adipose capsule)
－a thick adipose connective tissue capsule, surrounds the fibrous capsule. It acts as a shock absorber to protect the kidney from jolting and jarring.
肾筋膜(Renal fascia)
－on outside, surrounds both the kidney and suprarenal gland, holding these organs in place.
