Question 5

dorsal bud forms the

Answer 5

mesoderm

week 3

Question 9

pronephros are

Answer 9

rudimentary non functioning

Question 10

the mesonephros are

Answer 10

well developed and functions breifly

Question 11

the metanephros

Answer 11

become the permanent kidneys

Question 12

what happens to the pronephros during week 4

Answer 12

degenerates rapidly, leaving a duct to be used by the next kidney

Question 13

formations of the mesonephros during week 4

Answer 13

forms caudad to pronephros

- provides partial function while permanent kidneys continue to develop
