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.
The descending vasa recta, ascending vasa recta vessels, and the loop of Henle together form the countercurrent system of the kidney. In the afferent arteriole, blood is supplied at high pressure, which promotes filtration, and in the efferent arteriole, it is at low pressure, which promotes reabsorption .
In anatomy, arterial tree is used ... descending vasa recta; peritubular capillaries; gonadal. testicular artery in males; ... ascending branch; descending branch;
Vasa recta are straight arteries arising from arterial arcades (anastomoses of the jejunal and ileal arteries, branches of superior mesenteric artery) in the mesentery of the jejunum and ileum that supply the jejunum and ileum. [1] The vasa recta of the jejunum are long and few, compared to the ileum where they are numerous and short.
The left colic artery is a branch of the inferior mesenteric artery distributed to the descending colon, and left part of the transverse colon.It ends by dividing into an ascending branch and a descending branch; [1] the terminal branches of the two branches go on to form anastomoses with the middle colic artery, and a sigmoid artery (respectively).
The ascending limb drains urine into the distal convoluted tubule. The thick ascending limb is found in the medulla of the kidney, and the thick ascending limb can be divided into a part that is in the renal medulla and a part that is in the renal cortex. The ascending limb is much thicker than the descending limb.
The blood exiting the efferent arterioles of these nephrons enter the vasa recta, which are straight capillary branches that deliver blood to the renal medulla. These vasa recta run adjacent to the descending and ascending loop of Henle and participate in the maintenance of the medullary countercurrent exchange system.
