Urinary System-Blood flow through the kidney

Step 1

blood enters the kidney through a branch of the aorta called the renal artery, this blood contains glucose and O₂ and urea

Blood in the renal artery must have sufficient pressure or?

the kidney will not be able to filter the blood

step 2:

the renal artery branches into interlobular arteries, which further divide into afferent arterioles

step 3:

each afferent arteriole leads to a network of capillaries called a glomerulus

step 4:

blood leaves the capillaries of the glomerulus via an efferent arteriole

step 5:

blood from the efferent arterioles enter peritubular capillaries

step 6:

interlobular veins from the peritubular capillaries lead to the renal vein, which exits the kidney and returns blood to the inferior vena cava

Blood in the renal vein has had what removed?

all of its urea removed and should have exactly the right amount of H₂O and Na⁺
