Transcribed Image Text:The image is a detailed anatomical diagram of the nephron, the functional unit of the kidney. It is focused on illustrating the blood supply to the nephron and the structure of the renal corpuscle and tubules.
### Diagram Explanation:
- **Renal Blood Vessels**:
- The red vessels represent arteries (carrying oxygenated blood), while the blue vessels represent veins (carrying deoxygenated blood).
- The black arrow is pointing to the point of entry of the afferent arteriole, which brings blood into the glomerulus.
- **Glomerulus**:
- This is depicted as a tuft of capillaries within the renal corpuscle (circular structure at the top right), where blood filtration begins.
- The glomerulus is surrounded by Bowman's capsule (transparent structure).
- **Nephron Tubules**:
- The coiled structures represent the proximal convoluted tubule and distal convoluted tubule.
- The loop descending from the renal corpuscle and curving upwards is the Loop of Henle.
- The structures in beige represent the tubules of the nephron.
- **Peritubular Capillaries**:
- Surrounding the nephron tubules, they allow for exchange of substances between blood and filtrate.
This image is pivotal for understanding how blood is filtered through the kidneys and how waste is removed while essential nutrients and water are reabsorbed.
