Where does the blood come from on a period?

Answer 1

During a menstrual period, the blood comes from the shedding of the uterine lining, known as the endometrium. This shedding is triggered by a drop in estrogen and progesterone levels, which causes the blood vessels in the endometrium to constrict and then detach from the uterine wall. The blood is then expelled through the cervix and out of the vagina during menstruation.

Answer 2

During menstruation, the blood comes from the shedding of the lining of the uterus. The lining builds up throughout the menstrual cycle in preparation for a potential pregnancy, but if pregnancy does not occur, the lining is shed and expelled from the body as menstrual blood.

Answer 3

Well, darling, during a period, the blood comes from the shedding of the uterine lining. The uterus gets all dolled up every month, preparing for a potential baby, and when that doesn't happen, it throws a hissy fit and sheds its lining, causing some bleeding. It's like a monthly house party in your uterus, but instead of confetti, it's shedding tissue.

Answer 4

The discharge of blood comes from a woman's uterus. The bleeding is the result of cyclic hormonal changes. The ovaries produce eggs and female hormones. During the normal menstrual cycle, an egg will be released from one ovary. The egg travels from the ovary through a Fallopian tube to the Uterus. The cycle ends with the shedding of the inner lining of the Uterus, which causes menstruation.

Answer 5

The blood and tissues come from the uterus within the females body.

After ovulation hormonal changes trigger the uterine lining to build-up in preparation for the potential for that egg to be fertilized in order for the zygote to implant itself in the uterus in order to develop into a baby - the uterine tissue needs to be thick for this to happen. If a woman doesn't conceive then the hormone levels drop causing the uterine lining to break-down and this is menstruation. The whole process then starts a new the next cycle.
