Question 3

Describe the flow of blood through the kidneys.

Accepted Answer

Kidneys receive 20 to 25% of the resting cardiac output via the renal arteries.The renal arteries branch to form segmental arteries,which branch to form interlobar arteries (through renal columns)to arcuate arteries (over bases of pyramids)to interlobular arteries.The interlobular arteries branch to form afferent arterioles to each nephron.Afferent arterioles branch to form glomerular capillaries where filtration occurs.Glomerular capillaries merge to form efferent arterioles,which then branch to form peritubular capillaries.Juxtamedullary nephrons also have vasa recta capillaries around them.Peritubular capillaries merge to form peritubular veins and with the vasa recta to form interlobular veins to arcuate veins to interlobar veins.Blood exits the kidney via renal veins.
