Study Notes

Urinary System Components

The urinary system consists of the kidneys, ureters, urinary bladder, and urethra.

Kidney Structure and Location

The kidneys have other names, including "renes" and "nephri".
The kidney is a bean-shaped organ.
The kidney extends from the 12th thoracic vertebra to the 3rd lumbar vertebra.
The measurements of the kidney are approximately 10-12 cm in length, 5-6 cm in width, and 2.5 cm in thickness.
The weight of the kidney is approximately 120-150 grams.
The long axis of the kidney is directed downward and forward, while the transverse axis is directed forward and inward.
In the fetus, the kidney is located in the pelvic region.
The kidney moves downward during inhalation and returns to its original position during exhalation.
The normal part of the kidney that can be palpated is the lower pole.

Features of the Kidney

Each kidney has an upper pole, lower pole, anterior surface, posterior surface, lateral border, and medial border.

Covering of the Kidney

The kidney is covered by a fibrous capsule, perinephric fat (perirenal fat), and renal fascia.
Renal fascia consists of an anterior layer (fascia of Toldt) and a posterior layer (fascia of Zuckerkandl).
The kidney is also surrounded by paranephric fat (pararenal fat).

Relations of the Kidney

The anterior surface of the kidneys is related to the liver, duodenum, and colon.
The posterior surface of the kidneys is related to the diaphragm, psoas major, and quadratus lumborum.

Internal Structure of the Kidney

A coronal section of the kidney shows the cortex (outer region, lighter in color) and medulla (inner region, darker in color).
