Menstruation.
The flow of blood and tissue cells from the uterus is called menstruation. During menstruation, the lining of the uterus sheds and is expelled through the vagina. This process is accompanied by the flow of blood, which is a mix of tissue cells, uterine lining, and blood from the ruptured blood vessels in the uterus.
This process is called menstruation, and it occurs monthly in females of reproductive age. The shedding of the egg cell, uterine lining, and blood typically lasts for a few days and is a normal part of the menstrual cycle.
When you get your period it is uterus blood. Your period is the uterus shedding its lining if you do not get pregnant. All month your uterus builds up its lining for if your egg gets fertilized, and when/if it does not get fertilized, you have your period at the end of the month.
Menstruation is the process of the uterus lining shedding to ready itself for possible pregnancy next cycle. The uterine lining builds-up so that if a woman conceives the zygote can implant itself into the uterus to develop into a baby, if that doesn't happen the uterus lining sheds.
Menstruation results in the discharge of the uterus lining, consisting of blood and tissue.
Period blood comes from a girl's uterus. When a girl has her period, the uterus sheds the lining it builds up to feed an egg. When the egg isn't fertilized, the lining, which is made up of blood and clots, falls off of the walls and comes out of her cervix, the bottom of her uterus that opens into the end of the vagina, and then the blood flows down out of the opening of her vagina.
The uterus has a lining of blood in it. When the unfertilized egg passes through the uterus it sheds this lining which causes the blood to come out.
When you have your period, the lining of your uterus sheds along with blood. This lining is made up of tissue and blood vessels that build up in the uterus each month in preparation for a potential pregnancy. When fertilization does not occur, this lining is shed during menstruation, resulting in a mixture of blood and tissue being released out of the body.
Menstrual cramps occur due to the release of hormones called prostaglandins, which cause the uterus to contract and shed its lining. This contraction can result in pain and discomfort during menstruation. Additionally, the reduced blood flow to the uterus during contractions can cause cramps.
I think that if the relationship between oestrogen and the blood lining is that if it is low, there is a stop in the progression of blood lining and lining begins to break down, as oestrogen causes progesterone hormone that creates the thick mucus lining around the uterus and maintain it. When there is high concentration of oestrogen in the blood, it can help in maintaining the lining and creating the mucus in the uterus. Sometimes if there is a real high concentration in the blood, like when you take a contraceptive, it can cause blood clots to happen.
A blood clot is a clump of blood that forms in a blood vessel, while shedding of the uterine lining during menstruation is the natural process of the uterus releasing its lining.
The blood from the menstrual cycle is from the lining of the uterus or womb. The blood also contains mucosal tissue.
