what is periods in girls
Answers
Answer:
mensuration
Explanation:
A period is when a woman’s body releases tissue it no longer needs. This tissue comes from the uterus, which is where a baby (fetus) can develop in the female body. Every month or so, the uterus lining gets thicker to prepare for a fertilized egg if the woman becomes pregnant. If the egg doesn’t get fertilized, that lining is released from the body as blood through the vagina. This monthly process is called menstruation or a period.
Answer:
it is actually called menstruation which occurs in every female of ages between 10-50 once a month.
Explanation:
✓It is a 28 day cycle(average; it may vary), in which there is a heavy flow of endometrium lining along with degenerated if fertilization does not occur.
✓it has 3 phases:
1. menstrual phase: last for 1 to 5 days, heavy flow of menstrual fluid.
2. proliferative phase/follicular phase: days may vary depending on the length of cycle, causes development of follicles in ovary and endometrium lining of uterus.
ovulation occurs in the middle of the menstrual cycle.
3. luteal phase/secretory phase: always of 14 days, there is high level of progesterone present in blood which is secreted by corpus luteum(remains of follicle after ovulation) present in ovary. Progesterone maintains the endometrium lining in uterus.
As the level of progesterone falls, next cycle begins.
