Which of the following structures is directly involved in the process of menstruation?
Uterus
Each month the inner lining of the uterus (endometrium) thickens and becomes rich in blood vessels to receive a fertilised egg.
If fertilisation does not occur, this lining breaks down and is shed through the vagina along with blood and mucus; this is menstruation.
The ovary releases the egg and hormones, the fallopian tube carries the egg and is the site of fertilisation, and the liver is a digestive organ unrelated to the cycle.
Hence, the answer is Uterus.
