Answer:
Corteza renal, médula renal y pelvis renal.
Explicación:
Hay tres regiones principales del riñón, es decir, corteza renal, médula renal y pelvis renal. La corteza renal es la parte externa del riñón que se compone de glomérulos y túbulos contorneados. La corteza renal es responsable de la protección de las estructuras internas del riñón. La médula renal es la parte más interna del riñón que se divide en pirámides renales. La médula renal es responsable de la regulación de la concentración de orina. La pelvis renal es la región donde se unen los dos o tres cálices principales. La pelvis renal actúa como un embudo para la orina que fluye hacia el uréter.
