juxtamedullary nephron造句

• Cortical nephrons have a shorter loop of Henle compared to juxtamedullary nephrons.
• However, in most depictions of the nephron, it is a juxtamedullary nephron which is depicted.
• Some connecting tubules, usually associated with juxtamedullary nephrons, arch upwards before reaching the cortical collecting ducts.
• The longer loop of Henle in juxtamedullary nephrons create a hyperosmolar gradient that allows for the creation of concentrated urine.
• However, they surround the loop of Henle, forming the vasa recta, only in juxtamedullary nephrons and not in cortical nephrons.
• Efferent arterioles of juxtamedullary nephrons, the 15 % of nephrons closest to the medulla, send straight capillary branches that deliver isotonic blood to the renal medulla.
• These vessels branch off the efferent arterioles of juxtamedullary nephrons ( those nephrons closest to the medulla ), enter the medulla, and surround the loop of Henle.
• For cortical nephrons, a single network of capillaries, known as the peritubular capillaries, surrounds the entire renal tubule, whereas for juxtamedullary nephrons, the peritubular capillaries surround only the Henle ).
