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.
Juxtaglomerular cells (JG cells), also known as juxtaglomerular granular cells are cells in the kidney that synthesize, store, and secrete the enzyme renin. [1] They are specialized smooth muscle cells mainly in the walls of the afferent arterioles (and some in the efferent arterioles) [citation needed] that deliver blood to the glomerulus.
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 juxtaglomerular apparatus is part of the kidney nephron, next to the glomerulus. It is found between afferent arteriole and the thick ascending limb of the loop of Henle (distal straight tubule) of the same nephron. This location is critical to its function in regulating renal blood flow and glomerular filtration rate. [2] [3]
The findings suggest IL1B macrophages could be a promising therapeutic target to treat kidney cancer, given this cell type has already been targeted using existing drugs that prevent lung cancer.
The arterial arcades (intermesenteric arterial anastomoses or Riolan arcades [1]) are a series of anastomosing arterial arches between the arterial branches of the jejunum and ileum. Nearest the duodenum the mesenteric loops are primary, the vasa recta are long and regular in distribution, and the translucent spaces (lunettes) are extensive.
When renal blood flow is reduced (indicating hypotension) or there is a decrease in sodium or chloride ion concentration, the macula densa of the distal tubule releases prostaglandins (mainly PGI2 and PGE2) and nitric oxide, which cause the juxtaglomerular cells lining the afferent arterioles to release renin, activating the renin–angiotensin–aldosterone system, to increase blood pressure ...
The vasa recta have a similar loop shape so that the gradient does not dissipate into the plasma. [citation needed] The mechanism of counter current multiplication works together with the vasa recta's counter current exchange to prevent the wash out of salts and maintain a high osmolarity at the inner medulla. [citation needed]
