what happens to the ovum when it is (a)fertilized and(b)not fertilized in the fallopian tube
Answers
when not fertilized
Every 28 days or so, one mature egg is released from the ovary. This is called ovulation. After the egg is released, it moves into the fallopian tube where it stays for about 24 hours. If the egg is not fertilized during that time, the eggdisintegrates (breaks down) and menstruation (your period) begins 2 weeks later.
when fertilized
The corpus luteum releases a hormone that helps thicken the lining of your uterus, getting it ready for the egg. After the egg is released, it moves into the fallopian tube. It stays there for about 24 hours, waiting for a single sperm to fertilize it. All this happens, on average, about 2 weeks after your last period.
when fertilized it becomes an embryo and gets implanted in uterus
when not fertilized it is discarded in the form of menstrual cycle.
