Internal Kidney Anatomy

Numerous tubules and ducts make up the pyramids which gives the pyramids a striated appearance especially when viewed microscopically. Kidney anatomy encompasses all the internal and external tissue components that collectively form the structure of the kidney.

Internal anatomy a frontal section through the kidney reveals an outer region called the renal cortex and an inner region called the renal medulla figure 2512.

Internal kidney anatomy. A frontal section through the kidney reveals an outer region called the renal cortex and an inner region called the medulla link. The renal columns are connective tissue extensions that radiate downward from the cortex through the medulla to separate the most characteristic features of the medulla. The interlobular veins flow into the arcuate veins the interlobar veins and then the renal vein.

There are 8 18 renal pyramids in each kidney that on the coronal section look like triangles lined next to each other with their bases directed toward the cortex and apex to the hilum. These curve around the base of the pyramid as the arcuate arteries. This medial pocket contains the large blood vessels that pass in and out of the kidney and the tubes that conduct urine to the ureters and bladder.

In the medulla 5 8 renal pyramid s are separated by connective tissue renal columns. Next to the medulla is the renal sinus. Internal anatomy of the kidney overview the main unit of the medulla is the renal pyramid.

The kidneys are the main organs of the urinary system and are primarily responsible for removing toxins and other metabolic wastes from the blood. Renal internal anatomy kidney. The renal columns are connective tissue extensions that radiate downward from the cortex through the medulla to separate the most characteristic features of the medulla.

From the arcuate arteries arise a series of branches called the interlobular arteries in the cortex of the kidney. A frontal section through the kidney reveals an outer region called the renal cortex and an inner region called the medulla figure 2.
