Interlobular arteries Interlobular arteries Interlobular arteries (or cortical radiate arteries or cortical radial arteries) are renal blood vessels given off at right angles from the side of the arcuate arteries looking toward the cortical substance. The interlobular arteries pass directly outward between the medullary rays to reach the fibrous tunic, where they end in the capillary network of this part. These vessels do not anastomose with each other, but form end-arteries. In their outward course, they give off lateral branches, which are the afferent arterioles that supply the renal corpuscles. The afferent arterioles, then, enter Bowman's capsule and end in the glomerulus.
Hereditary hemorrhagic telangiectasia noted by cyanosis (bluish discoloration of the lips and skin), clubbing of the fingernails (often encountered in chronically low oxygen levels), and a humming noise over the affected part of the lung detectable by stethoscope. The symptoms produced by AVMs in the liver depend on the type of abnormal connection that they form between blood vessels. If the connection is between arteries and veins, a large amount of blood bypasses the body's organs, for which the heart compensates by increasing the cardiac output. Eventually congestive cardiac failure develops ("high-output cardiac failure"), with breathlessness and leg swelling among other problems. If
