21

glassy membrane

advanced atresia

22

In the corpus luteum, follicular/granulosa cells give rise to ______ cells and secrete ____ and ____.

follicular lutein cells and secrete progesterone and estrogen

23

In corpus luteum, theca interna cells give rise to ______ cells and secrete ____ and ____.
