Final answer:
The renal tubule consists of three parts: the proximal convoluted tubule (PCT), the loop of Henle, and the distal convoluted tubule (DCT).
Step-by-step explanation:
The renal tubule consists of three parts: the proximal convoluted tubule (PCT), the loop of Henle, and the distal convoluted tubule (DCT).
The PCT is located in the renal cortex and is responsible for reabsorbing nutrients, ions, and water from the filtrate.
The loop of Henle forms a loop through the renal medulla and has descending and ascending limbs. It plays a key role in concentrating urine.
The DCT is also located in the renal cortex and is responsible for fine-tuning the reabsorption and secretion of ions and maintaining the pH balance of the urine.
