Question

Part C - Follicles Kate thought it was interesting that, after the release of a mature oocyte from the ovary, the follicle it was released from took on a new role. What happens to the follicle

Answer 1

Answer: The follicle assumes a new role which is:

--> the secretion of hormone PROGESTERONE and

--> OESTROGEN

Explanation:

The cycle in the female reproductive system of humans which tak s 28dayd to complete is known as menstrual cycle. At the beginning of the menstrual cycle, several primary oocytes begin to develop. Each oocyte is surrounded by actively dividing granular cells from which it receives nutrients. The whole structure is called a FOLLICLE.

A developing follicle secretes OESTROGEN.

Usually, only one of the developing follicles becomes mature to produce an ovum. As the follicle matures, it becomes filled with fluid and the oocyte is pushed to one side. Ovulation occur when there is release of an ovum from a mature follicle.

The ruptured mature follicle develops into a CORPUS LUTEUM which is a solid yellow body that secretes the hormone PROGESTERONE. This is the hormone that helps to maintain the early stages of pregnancy if fertilization and implantation of embryo occurs. In the absence of pregnancy, the corpus luteum shrivels.
