The membrane that functions in respiration in the
embryo is the
A. amnion.
B. allantois.
C. chorion.
D. umbilical cord.
E. yolk sacembryo is the
A. amnion.
B. allantois.
C. chorion.
D. umbilical cord.
Kaplan says the answer is B. but chorion also plays a role in gas exchange. So does allantois play a bigger role then?
Thanks
