Vascular segments of kidney. Anterior and posterior view
This specimen shows the vascular segments of the kidneys in the anterior and the posterior view. The kidneys are a pair of bean-shaped excretory organs situated on the posterior abdominal wall on either side of the vertebral column. The renal arteries enter the hilum of the kidneys and divided into anterior and posterior divisions. These divisions will give rise to the segmental arteries. The anterior division is larger and gives four segmental arteries to supply the apical, upper anterior, middle anterior and lower segments, whereas, the posterior division supplies only the posterior segment. The posterior division is smaller and supplies only the posterior segment. These segmental arteries are end arteries. Therefore, the vascular segments permit the segmental resection of the kidneys.
