- A$D$ - Cortex - It is the outer part of the kidney and does not contain any parts of the nephrons.
- B$A$ - Adrenal gland - Located at the anterior part of the kidney,it secretes catecholamines which stimulate glycogen breakdown.
- C$B$ - Renal pelvis - $A$ broad,funnel-shaped space inside the hilum,directly connected to the loop of Henle.
- D$C$ - Medulla - The inner part of the kidney that contains the entire nephron structure.
