Where do the kidneys lie?

Anatomical Position. The kidneys lie retroperitoneally (behind the peritoneum) in the abdomen, either side of the vertebral column. They typically extend from T12 to L3, although the right kidney is often situated slightly lower due to the presence of the liver. Each kidney is approximately three vertebrae in length.

The upper poles are normally oriented more medially and posteriorly than the lower poles.

Are the kidneys located behind the parietal peritoneum?

The inside wall is covered by the parietal peritoneum. The kidneys are located behind the peritoneum, in the retroperitoneum, outside the abdominal cavity. The viscera are also covered by visceral peritoneum. Between the visceral and parietal peritoneum is the peritoneal cavity, which is a potential space.

Why is the position of the kidney described as retroperitoneal?

The left kidney sits a bit higher in the body because of the size of the liver, which is also on the right side. … The kidneys are considered “retroperitoneal” organs, which means they sit behind a lining in the abdominal cavity, unlike all other abdominal organs.

Which layer of support tissue holds the kidneys in the retroperitoneal position?

This means they are retroperitoneal. Each kidney is held in place by connective tissue, called renal fascia, and is surrounded by a thick layer of adipose tissue, called perirenal fat, which helps to protect it.
