One renal vein drains each kidney. [citation needed] A renal vein is situated anterior to its corresponding accompanying renal artery.The renal veins empty into the inferior vena cava, entering it at nearly a 90° angle.
Hypothalamus: The hypothalamus is a key regulator of the autonomic nervous system. The endocrine system has three sets of endocrine outputs [5] which include the magnocellular system, the parvocellular system, and autonomic intervention. The magnocellular is involved in the expression of oxytocin or vasopressin.
The nephron is the minute or microscopic structural and functional unit of the kidney.It is composed of a renal corpuscle and a renal tubule.The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman's capsule.
The kidney and nervous system communicate via the renal plexus, whose fibers course along the renal arteries to reach each kidney. [22] Input from the sympathetic nervous system triggers vasoconstriction in the kidney, thereby reducing renal blood flow . [ 22 ]
In the mammalian kidney, they follow two markedly different courses, depending on the location of the glomeruli from which they arise. In the mammalian kidney, about 15% of glomeruli lie close to the boundary between the renal cortex and renal medulla and are known as juxtamedullary glomeruli. The rest are simply undifferentiated cortical ...
The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate.
The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).
Hepatorenal syndrome usually affects individuals with cirrhosis and elevated pressures in the portal vein system (termed portal hypertension). While HRS may develop in any type of cirrhosis, it is most common in individuals with alcoholic cirrhosis, particularly if there is concomitant alcoholic hepatitis identifiable on liver biopsies. [9]
