Question

Differentiate between the ''columns of Bertin'' and duct of Bellini''.

Answer 1

• COLUMNS OF BERTIN	DUCT OF BELLINI
  The renal column (or Bertin column, or column of Bertin) is a medullary extension of the renal cortex in between the renal pyramids.	Ducts of Bellini are also called as Papillary ducts. The duct of Bellini represents the most distal portion of the collecting duct.
  It allows the cortex to be better anchored.	They receive renal filtrate (precursor to urine) from several medullary collecting ducts and empty into a minor calyx. Papillary ducts continue the work of water reabsorption and electrolyte balance initiated in the collecting tubules.
