Adaptation of a Nephron for Selective Reabsorption

1. a) Length: Provides a large surface area for material reabsorption. 
2. b) Tubule Structure: Made of a simple layer of cells to facilitate easy osmosis.
3. c) Capillary Network: Surrounded by dense capillaries for efficient diffusion.
4. d) Mitochondria: Supply ATP for active transport processes.
5. e) Membrane Foldings: Highly folded membranes (villi) increase the area for reabsorption.
