|
|
|
What does the ureteric bud induce the metanephric mesoderm to do
|
form tubules that will form urine
|
|
|

|
urine collecting structures
ureters renal pelvis major/minor calyces collecting ducts/tubules |

|
Before they ascend from the pelvis, the kidneys blood supply was from the
|
iliac arteries/veins
|
|
|
Why is there such considerable variation in the blood supply to the kidney in adults?
|
kidneys ascend from pelvis and change blood supply along the way

False.
Still functional just ectopic |
