Question
### Labeling the Nephron Structure #### Instructions: Examine the diagram of the nephron below. Please label the structures and place numbers to indicate the sequence of filtrate flow through the nephron. Additionally, mark a star at the site of filtration. Identify the cortex and medulla on the image. #### Diagram Explanation: The diagram illustrates the structure of a nephron, a functional unit of the kidney. Key components of the nephron in the diagram include: 1. **Afferent Arteriole**: Carries blood to the glomerulus. 2. **Glomerulus**: A network of capillaries where filtration occurs. (Star site) 3. **Efferent Arteriole**: Transports blood away from the glomerulus. 4. **Proximal Convoluted Tubule**: The first part of the nephron tubule where initial absorption occurs. 5. **Loop of Henle**: Extends into the medulla, crucial for concentration of urine. 6. **Distal Convoluted Tubule**: Further modification of the filtrate. 7. **Collecting Duct**: Final passage for urine, influencing its final concentration. #### Image Labels: - **Cortex**: The outer layer of the kidney where the glomerulus and the proximal and distal convoluted tubules are located. - **Medulla**: The inner region of the kidney through which the loop of Henle and collecting duct pass. By associating the labels and directions on the diagram, learners can visualize the complex process of urine formation within the kidney's cortex and medulla.
