From Kaplan diagnostic test:
Which of the following is involved in respiration and excretion and develops into the placenta in humans?
A. Chorion <-- I chose this answer (develops into placenta)
B. Allantois <-- this is the answer they gave
C. Amnion
D. Yolk sac
E. Placenta
Another poorly worded problem? I understand that excretion is handled mainly by the allantois, but chorion + endometrium = placenta.
