Do Juxtamedullary nephrons have vasa recta?
Juxtamedullary Nephron: The long loop of Henle of the juxtamedullary nephrons is surrounded by a large vasa recta network.
What is the function of the Juxtamedullary vasa recta?
In juxtamedullary nephrons, the efferent arterioles give rise to the vasa recta, which plunges down into the renal papilla to supply blood to that tissue. The descending vasa recta and ascending vasa recta make a loop. The vasa recta forms a capillary network within the renal medulla.
Is the vasa recta associated with the nephron loop?
One nephron drains into one collecting tubule, and several collecting tubules drain into a collecting duct. Peritubular capillaries are associated with the convoluted tubules, while vasa recta are associated with the nephron loop.
What are vasa recta associated with?
The vasa recta of the kidney, (vasa rectae 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.
What are juxtamedullary nephrons?
In other words, a juxtamedullary nephron is a nephron whose renal corpuscle is near the medulla, and whose proximal convoluted tubule and its associated loop of Henle occur deeper in the medulla than the other type of nephron, the cortical nephron.
Do juxtamedullary nephrons have peritubular capillaries?
In the juxtamedullary nephrons, the peritubular capillaries have a specialization called the vasa recta, which are long, hairpin-shaped blood vessels that follow the same course as the loop of Henle. The vasa recta serve as osmotic exchangers for the production of concentrated urine.
What are Juxtamedullary nephrons?
Juxtamedullary nephrons have a glomerulus near the junction of the cortex and medulla and they have loops of Henle that penetrate deep into the medulla.
How do cortical and Juxtamedullary nephrons differ in function?
Cortical vs Juxtamedullary Nephrons The main function of cortical nephrons is to carry out the major regulatory and excretory functions in the human body while the main function of the Juxtamedullary nephrons is to concentrate or dilute the urine.
Do Juxtamedullary nephrons have peritubular capillaries?
What structure receives blood from the vasa recta of a Juxtamedullary nephron?
Cortical nephrons are responsible for producing concentrated urine. What structure receives blood from the efferent arteriole of a juxtamedullary nephron? The efferent arteriole of a juxtamedullary nephron carries blood to the vasa recta.
Where are juxtamedullary nephrons?
Juxtamedullary nephrons are found only in birds and mammals, and have a specific location: medullary refers to the renal medulla, while juxta (Latin: near) refers to the relative position of the renal corpuscle of this nephron – near the medulla, but still in the cortex.
What is a cortical and Juxtamedullary nephron?
Cortical nephrons either have short or absent loops of Henle. Only juxtamedullary nephrons have long loops of Henle, which plunge into the renal medulla and create a hypersomotic interstitium via counter current multiplication.
