Both Vasa Recta and Peritubular Capillaries emerge from the efferent arteriole of the kidney. They provide oxygen and nutrients in the surrounding region. Here, let's look at the differences between Vasa Recta and Peritubular Capillaries.
The vasa recta of the kidney, (vasa recta renis) are the straight arterioles, and the straight venules of the kidney, – a series of blood vessels in the blood supply of the kidney that enter the medulla as the straight arterioles, and leave the medulla to ascend to the cortex as the straight venules.
Oct 30, 2023 · In cortical nephrons (loop of Henle does not extend deep into the medulla), the capillary beds are called peritubular capillaries; while in juxtamedullary nephrons (loop of Henle extends deep into the medulla), the capillary beds are called vasa recta. These capillary beds facilitate blood pressure regulation and ionic homeostasis both ...
Oct 30, 2023 · The two limbs work in parallel, with the surrounding vasa recta capillaries, to adjust the filtrate’s salt (e.g. sodium, chloride, potassium) and water levels. More specifically, the descending limb is highly permeable to water, less permeable to solutes, while the ascending limb is the opposite.
Jan 12, 2024 · The vasa recta are an ingenious network of the renal medulla's function, allowing the kidneys to regulate water and solute balance effectively. By enabling countercurrent exchange, these vessels produce concentrated urine while conserving water, a critical adaptation for maintaining homeostasis.
Feb 14, 2024 · Vasa recta, which are capillary beds surrounding the nephron loops and maintain the osmotic gradient required for water reabsorption; Interstitium, which comprises the extravascular intertubular spaces of the renal parenchyma.
The vasa recta capillaries are long, hairpin-shaped blood vessels that run parallel to the loops of Henle. The hairpin turns slow the rate of blood flow, which helps maintain the osmotic gradient required for water reabsorption.
The vasa recta, the capillary networks that supply blood to the medulla, are highly permeable to solute and water. As with the loop of Henle, the vasa recta form a parallel set of hairpin loops within the medulla (see Chapter 2). Not only do the vasa recta bring nutrients and oxygen to the medullary nephron segments but, more importantly, they ...
Discuss the function of the peritubular capillaries and vasa recta; Identify the location of the juxtaglomerular apparatus and describe the cells that line it; Describe the histology of the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting ducts
The vasa recta are seen only in the juxtamedullary nephron and characterised as being long and straight. This allows the countercurrent mechanism to work and also is the main location for water reabsorption.
