Study Notes
Proximal Tubule Characteristics
- The most distinctive characteristic of the proximal tubule is the presence of microvilli, which increase the surface area for reabsorption.
Microvilli Function
- Microvilli in the proximal tubule increase the surface area for reabsorption of nutrients and ions from the filtrate.
Mitochondria Location
- Mitochondria are largely found in the basal region of the cells in the proximal tubule, providing energy for the active transport of substances.
Proximal Tubule Segment
- The proximal tubule is the segment of the nephron that begins from the renal pole of the Bowman's capsule to the beginning of the loop of Henle.
Transition from Bowman's Capsule
- The cells lining Bowman's capsule, known as podocytes, abruptly transition to proximal tubule epithelial cells.
