Which of the following structures are components of a nephron?

• A. Renal corpuscle and renal tubule
• B. Renal pelvis and ureter
• C. Glomerulus and collecting duct only
• D. Loop of Henle and renal capsule only

Answer: (A)

Verified step by step guidance

1. Understand the anatomy of the nephron: The nephron is the functional unit of the kidney responsible for filtering blood and forming urine. It consists of two main components: the renal corpuscle and the renal tubule.
2. Break down the renal corpuscle: The renal corpuscle includes the glomerulus (a network of capillaries) and Bowman's capsule (a structure that surrounds the glomerulus and collects the filtrate).
3. Examine the renal tubule: The renal tubule is divided into several segments, including the proximal convoluted tubule, Loop of Henle, distal convoluted tubule, and the collecting duct. These structures are involved in reabsorption and secretion processes.
4. Eliminate incorrect options: The renal pelvis and ureter are not part of the nephron; they are structures involved in urine transport. Similarly, the glomerulus and collecting duct are components of the nephron but do not represent the nephron as a whole. The Loop of Henle and renal capsule are parts of the nephron but do not encompass all its components.
5. Select the correct answer: Based on the anatomy of the nephron, the correct components are the renal corpuscle and renal tubule, as these encompass all the structures involved in filtration and urine formation.
