The process by which an oocyte bursts from an ovary and usually enters an oviduct (Fallopian tube) is called ovulation.

Here are the steps of this process:

1. The menstrual cycle begins with the menstrual phase, which is marked by the shedding of the uterine lining and bleeding. This phase lasts for about five days.

2. Following the menstrual phase is the follicular phase. During this phase, the pituitary gland releases a hormone called follicle-stimulating hormone (FSH). This hormone stimulates the growth of several ovarian follicles, each containing one oocyte.

3. As the follicular phase progresses, one follicle becomes dominant while the others degenerate. The dominant follicle continues to grow and mature under the influence of FSH and another hormone called luteinizing hormone (LH).

4. Around the middle of the menstrual cycle, a surge in LH triggers ovulation. This is the process where the mature oocyte bursts from the dominant follicle and ovary.

5. The released oocyte then enters the Fallopian tube, where it can be fertilized by a sperm cell to form a zygote. If fertilization does not occur, the oocyte will degenerate and be expelled from the body during the next menstrual phase.
