The Proximal convoluted tubules, descending loop , ascending loop of henle and the distal convoluted tubules. Though the collecting ducts determine the final concentration of urine, an author states that it's not a part of the nephron.
The distal convoluted tubule is the portion of the nephron that empties into the collecting ducts. It is the last segment of the nephron.
That would be the nephron.

The collecting tubule
The portion of the nephron that attaches to the collecting duct is the distal convoluted tubule. It is responsible for fine-tuning the reabsorption of water and electrolytes before the filtrate eventually exits the nephron.
The portion of the nephron that dips into the medulla of the kidney is called the loop of Henle. This structure plays a key role in concentrating urine by creating a concentration gradient in the kidney.
