Definição e Significado de "renal medulla"

What is "renal medulla"?

The renal medulla is the innermost region of the kidney, located deep within the renal cortex. It consists of renal pyramids, which contain tiny tubules that help in the formation of urine. The renal medulla plays a crucial role in regulating the concentration and volume of urine by reabsorbing water and concentrating waste products. It also houses the renal papilla, where urine is collected and transported to the renal pelvis before being excreted from the body.
