Explanation:
It begins at puberty and the onset of the menstrual cycle is called ‘menarche’.
The process includes cyclic changes in the ovaries and in the uterus, both simultaneously.
In the ovaries, an ovum develops and matures and then released.
In the uterus, a thick spongy inner lining develops anticipating pregnancy.
If the egg is fertilized, pregnancy occurs.
If fertilisation does not occur, the released egg and the thickened lining of the uterus along with its blood vessels are shed off.
This causes bleeding in women which is called menstruation.
The menstrual cycle stops in women anywhere between 45 to 52 years.
Stopping of the menstrual cycle is called ‘menopause‘.
The years between menarche and menopause marks the reproductive age of a woman where she is able to bear a child.
The monthly discharge of blood from the uterus of a non - pregnant woman from puberty to menopause is called menstruation. Mentruation occurs once in about 28 to 30 days.
