GENERAL HISTOLOGY

Detailed explanation-1: -The fertilized egg attaches to the lining of the uterus. The placenta then develops. The placenta transfers nutrition and oxygen to the fetus from mother. If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation.

Detailed explanation-2: -What is ovulation? Ovulation is a phase in the menstrual cycle when your ovary releases an egg (ovum). Once an egg leaves your ovary, it travels down your fallopian tube where it waits to be fertilized by sperm. On average, it happens on day 14 of a 28-day menstrual cycle.

Detailed explanation-3: -If sperm fertilizes that egg, the fertilized egg implants into your uterine lining and pregnancy occurs. If the egg isn’t fertilized or doesn’t implant (pregnancy doesn’t occur), you’ll get your period. Your luteal phase is over when you get your period.

Detailed explanation-4: -The luteal phase If a fertilised egg implants in the lining of the uterus, the corpus luteum continues to produce progesterone, which maintains the thickened lining of the uterus. If pregnancy does not occur, the corpus luteum dies, progesterone levels drop, the uterus lining sheds and the period begins again.

Detailed explanation-5: -During menstruation, or your period, you shed your uterus lining (endometrium) through your vagina. The follicular phase begins on the first day you menstruate. It lasts until ovulation, when one of your ovaries releases a mature egg.
