During the first trimester, hCG produced from the chorion maintains the corpus luteum. What is the purpose of maintaining the corpus luteum?

Select one:

 The corpus luteum ensures that the endometrium does not break down during the first trimester.

The corpus luteum supports the formation of the placenta.

The chorion forms the fetal part of the placenta, and the corpus luteum supports the maternal part of the placenta.

 The corpus luteum produces relaxin, which thickens the endometrium.

 

 

How does the human body ensure that another pregnancy does not occur during embryonic and fetal development?

Select one:

High levels of estrogen

 Low levels of oxytocin

Low levels of LH

 High levels of FSH
