Answer 1

1. The primary follicle, tertiary follicle with antrum B, and Graafian follicle C are depicted in the image. LH and FSH are secreted by the pituitary gland’s anterior lobe, and FSH promotes the formation of ovarian follicles, or from A to B to C.
2. Estrogen is the hormone that A and B secrete.
3. The luteum, or corpus luteum, is represented by D in the picture. Progesterone, which it secretes, helps in endometrial maintenance.
