Hypertensive kidney disease this situation, the kidney supplied blood by the narrowed renal artery suffers from inadequate blood flow, which in turn causes the size of the kidneys to decrease. Other consequences include arterial stiffening, which involves a gradual breakdown of elastic fibers and intima (the innermost layer of a blood vessel) thickening. An alternative mechanism of hypertensive nephropathy is prolonged glomerular hypertension and hence glomerular hyperfiltration. These can occur simultaneously but not necessarily. The idea is that hypertension results in sclerosis of the glomeruli which ultimately means reduced kidney function. As a compensatory mechanism, the unaffected nephrons (specifically, the preglomerular arterioles) vasodilate
Inferior vesical artery Inferior vesical artery The inferior vesical artery or inferior vesicle artery is an artery in the pelvis that supplies the lower part of the bladder. The inferior vesical artery is a branch (direct or indirect) of the anterior division of the internal iliac artery. It frequently arises in common with the middle rectal artery, and is distributed to the fundus of the bladder. In males, it also supplies the prostate and the seminal vesicles. The branches to the prostate communicate with the corresponding vessels of the opposite side. Some texts consider it to be found only in males, and cite
