Notes

The duct of Bellini, also known as the papillary duct, is a structure in the kidney that plays a crucial role in the urinary system. It is the final segment of the collecting duct system and is responsible for draining urine into the renal pelvis.

Structure

The duct of Bellini is located in the medulla of the kidney. It is formed by the convergence of several collecting ducts, which are part of the nephron structure. The duct of Bellini opens at the tip of the renal papilla, where it releases urine into the minor calyx.

Function

The primary function of the duct of Bellini is to transport urine from the collecting ducts to the renal pelvis. This process is essential for the excretion of urine from the body. The duct of Bellini also plays a role in the concentration of urine, as it is involved in the reabsorption of water and solutes.

Clinical significance

Obstruction or damage to the duct of Bellini can lead to urinary tract issues, such as hydronephrosis or urinary tract infections. It is important in the context of certain kidney diseases and conditions that affect the collecting duct system.

History

The duct of Bellini is named after the Italian anatomist Lorenzo Bellini, who first described it in the 17th century. His work laid the foundation for the understanding of the renal system and its functions.
