Vasa recta are a unique kind of peritubular capillary that feeds the kidney's medulla with oxygen and nutrients, whereas peritubular capillaries are capillaries that emerge from the efferent arteriole. This is the main distinction between the two types of capillaries.
Vasa Recta: What are they?
- The unique peritubular capillaries known as vasa recta supply oxygen and nutrients to the kidney's medulla. They especially come from juxtamedullary nephrons' efferent arterioles and wind around those organelles' Henle loops.
- They also create a parallel series of hairpin loops inside the kidney's medulla. Vasa recta have high water and solute permeability.
Peritubular Capillaries: What Are They?
- The efferent arteriole that emerges from the glomerulus gives rise to the capillary network known as peritubular capillaries. The renal cortex receives nutrients and oxygen via peritubular capillaries.
- As a result, the renal cortex contains a greater percentage of peritubular capillaries. They encircle the distal and proximal tubules.
