Kidney Where Vessels Come And Go. The renal artery is one of these two blood vessels. It is also the point of exit for the ureters.
Close to the renal hilus each artery gives off small branches to the adrenal gland and ureter and then branches into anterior and posterior divisions. There are two blood vessels leading off from the abdominal aorta that go to the kidneys. Internally the kidney has three regions an outer cortex a medulla in the middle and the renal pelvis in the region called the hilum of the kidney.
The kidney participates in whole body homeostasis regulating acid base balance electrolyte concentrations extracellular fluid volume and blood pressure.
In a nephron afferent vessels take blood into the kidneys whereas the efferent vessels take blood away from the nephrons. In addition passive countercurrent exchange by the vessels carrying the blood supply to the nephron is essential for enabling this function. The kidney functions only because of presence of nephrons. The renal artery enters through the hilum which is.
