Correct option is A
The correct answer is (A) The uterine lining is shed.
During menstruation, the lining of the uterus breaks down and exits the body as menstrual blood. This occurs when an egg is not fertilized, causing hormone levels to decrease.
Hormones: Rising estrogen levels help the ovaries release an egg (ovulation).
- Progesterone prepares the uterus to receive a fertilized egg.
- If the egg is not fertilized, estrogen and progesterone levels drop, triggering menstruation.
Uterine Lining: The uterus lining thickens each month to support a possible pregnancy.
- If there is no fertilized egg, the lining sheds and leaves the body as a period.
Bleeding: Menstrual bleeding typically lasts around five days.
Pain: Some people experience cramps in the lower abdomen or back, especially during the first couple of days.
Other Symptoms: Common symptoms include mood swings, headaches, tiredness, food cravings, bloating, and breast tenderness.
Information booster:
- Menstrual Cycle:A typical menstrual cycle is about 28 days long.
