Structure of Kidney

Internal Structure of a Kidney:

Each kidney is enclosed in a thin, fibrous covering called the capsule. A renal artery brings blood into the kidney, along with nitrogenous waste materials. After filtration in the kidney, the purified blood leaves the kidney through a renal vein. Two distinct regions can be seen in the section of a kidney:

  • an outer, dark, granular cortex and
  • an inner, lighter medulla.
  • The hollow space from where the ureter leaves the kidney is called the pelvis
