Which is considered a primary layer of the kidney?
- Renal sinus
The renal sinus is a cavity within the kidney. It is occupied by blood vessels, fat, nerves, and the renal pelvis and renal calyces; however, it is not one of the primary layers of the kidney.
- Renal pelvis
The renal pelvis is held within the renal sinus, a cavity within the kidney. It is not, however, a primary layer of the kidney.
- Renal pyramid
The renal pyramid is held within the renal medulla; it is not, however, a primary layer of the kidney.
- Renal medulla
The renal medulla is the interior, or inside layer, of the kidney where the primary functions of this organ occur. The primary functions of the kidney is the filtration of waste productions and the elimination of fluid from the body.
Each kidney has two primary layers that assist with the function of urine production.
The two primary layers of the kidneys include the renal medulla and the renal cortex. The renal medulla is the inside layer of the kidneys. The renal cortex is the outer layer of the kidneys.
