Which structure in the nephron collects urine from the distal convoluted tubule?

• A. Glomerulus
• B. Proximal convoluted tubule
• C. Loop of Henle
• D. Collecting duct

Answer: (D)

Verified step by step guidance

1. Understand the basic structure of the nephron, which is the functional unit of the kidney. It consists of several parts: the glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and the collecting duct.
2. Recognize the role of each part of the nephron. The glomerulus is involved in the filtration of blood, the proximal convoluted tubule reabsorbs nutrients, the loop of Henle concentrates urine, and the distal convoluted tubule further adjusts the composition of urine.
3. Identify the pathway of urine flow through the nephron. After the distal convoluted tubule, urine flows into the collecting duct.
4. Understand that the collecting duct is responsible for collecting urine from multiple nephrons and transporting it to the renal pelvis.
5. Conclude that the structure in the nephron that collects urine from the distal convoluted tubule is the collecting duct.
