The vasa recta are found in the kidneys, specifically in the renal medulla. They are long, straight capillaries that extend from the peritubular capillaries and surround the nephron's loops of Henle. Their primary role is to supply blood to the medullary tissue and help maintain the osmotic gradient necessary for urine concentration.
What else can I help you with?
What is the Capillary network that surrounds the loop of Henle?
the vasa recta MasteringAandP = Vasa Recta
The name of the blood vessels that are found in the medulla as part of the vasa recta are the?
peritubular capillaries
What normally contains blood Bowman's capsule vasa recta loop of Henle collecting duct or proximal tubule?
The vasa recta. It is the main capillary that collects the filtered blood from the afferent tubule.
Capillary loops located in the medulla are also known as?
Vasa Recta
The vasa recta is a specialized portion of the what?
The efferent areterioles serving the juxtamedullay nephrons tend not to break up into preitubular capullaries. Instead they form bundles of long straight vessels called vasa recta that extend deep into the medulla paralleling the longest loops of Henle. The play and important role in forming concentrated urine. they also reclaim most of that filtrate
What is another name for vasa recta?
straight arterioles that follow the nephron loop
How do you distinguish jejunum and ileum in an operation?
jejunum •Thick wall •Many large folds •Wide lumen •Long vasa recta •Less fat •Redder ileum •Thinner wall •Fewer small folds •Narrower lumen •Short vasa recta •More fat
What is the capillary loop that extend from the efferent arteriole and run along loop of henle of juxtamedullary nephrons?
Vasa Recta
The net action of the vasa recta is to remove water from and dilute solutes in the interstitial fluid of the renal medulla?
The vasa recta is involved in maintaining the concentration gradient in the renal medulla by removing water and diluting solutes from the interstitial fluid. This helps in the reabsorption of water and prevents the washout of concentrated urine.
The bowman's capsule contain a podocyte a vasa recta a fenestrated capillarry an efferent arteriole?
The Bowman's capsule is part of the kidney's nephron structure and contains a cluster of capillaries called a glomerulus that is surrounded by podocytes. The efferent arteriole exits the glomerulus, and the vasa recta are responsible for reabsorbing nutrients and water from the kidney tubules. Fenestrated capillaries in the glomerulus allow for efficient filtration of blood.
What happens as blood flows upward in the vasa recta?
As blood flows upward in the vasa recta, it experiences an increase in oxygen and nutrient concentration while losing water and solutes due to the surrounding osmotic gradient in the renal medulla. This process helps to maintain the hyperosmotic environment necessary for urine concentration. Additionally, the vasa recta's countercurrent exchange mechanism ensures that the blood remains rich in oxygen and nutrients, supporting the metabolic needs of the renal medulla. Overall, this upward flow contributes to the efficient functioning of the nephron and the regulation of water balance in the body.
What describes the process in which molecules are selectively removed from the tubule moved into interstitial space and removed from the kidneys by the peritubular capillaries and the vasa recta?
Reabsorption
