QUESTION
Which of these two hormones are produced from placenta in some of the species?
OPTIONS
(A) Relaxin and lactogen
(B) Progesterone and estrogen
(C) hCG and PGE2
(D) All of the above
ANSWER
(D) All of the above
EXPLANATION
Placental endocrine products differ among species and can include relaxin, placental lactogen, progesterone, estrogens, chorionic gonadotropins, and prostaglandins such as PGE2. Human chorionic gonadotropin is specifically associated with human and related primate placentation, rather than being universal in domestic animals. Because the question explicitly refers to some species, each listed pair is possible and all of the above is the inclusive answer.
