The columns of Bertin and ducts of BellinI both are the part of the kidney used in blood filtration.
In the column of bertin renal column is the extension of medulla of the renal cortex whereas the ducts of bellini are the most distal part of the filtrate collecting duct in the kidney.
Columns of bertin help in filtration of blood and the duct of bellini helps in reabsorption of electrolytes.
Columns of Bertin are the ascending part of the nephron cell in the kidney but the Duct of bellini is the descending part of the kidney cell.
