What are caused by the uterus contracting to expel its lining?
Cramps are caused by the uterus to expel its lining.
Why does your stomache hurt when on your period?
The lining of your uterus builds up over the month in preparation for an egg to be implanted when fertilized. If this does not happen your hormones start the uterus to contract and expel the blood. When your uterus contract severely you feel it as cramping in your lower abdomen.

Because during your period your uterus contracts which causes the cramping pain to expel the uterine lining. During labor the uterus does the same action to help deliver a baby.
Why do you have cramps when you on your periods?
After a woman enters puberty, her cycle begins. At the end of the cycle (which is plus of minus 28 days) the bloody inner lining of the uterus breaks down when the egg was not fertilized. The liquification of that bloody lining is what is expelled at the end of the cycle (period). The uterus contracts to help the bloody lining expel. The uterine contractions are what cause the feeling of cramps.
Why would you start a period two days after finishing a period?
The body may still have some of the uterus wall lining left to expel and it may take longer to be expelled.
Why do girls have cramps during periods?
The uterus is a muscle. During menses it contracts to expel the uterine lining and menstrual blood. This is a mild from of the contraction it does to push out a baby. The contraction can press against a blood vessel and cut off the blood supply. This pinching off of the blood supply causes the cramping.Answer 2:I believe it's because of the shedding of the uterus lining.
What answers the why should the uterus be strong?
To support and then expel the fetus.
What is the role of the uterus in the reproductive system?
The uterus is the organ in females which will hold and nourish the growing embryo/fetus after fertilization. It produces a lining rich in proteins and blood vessels which, if not subject to implantation of a fertilized egg, will be shed in menstruation. If implantation does occur, the lining remains and grows, eventually forming the placenta which will nourish the developing fetus until birth. The uterus also is critical during the birth process. Strong smooth muscle contractions are what expel the baby from the uterus through the vagina and out into the world, also known as labor pains.
Why does the uterus have thick muscular walls?
The uterus has thick walls because a fertilized egg would need a thick lining in order to implant and begin to grow and develop. The uterus is sterile and has no bacteria present, however large quantities of debris and bacteria is brought into the uterus with the sperm. Therefore, the walls must be strong and muscular because uterine contraction has to occur to expel fluid, dead sperm and bacteria out from the uterus and through the open cervix.
What happens to the uterus wall during menstruation?
Each month a lining builds up in the uterus so an egg may implant for pregnancy. When that doesn't happen it sheds and that is menstruation. So, basically each month a woman has a new lining in the uterus.
Why is menstration painful?
Menstruation can be painful because the uterus contracts to expel the blood, something like labour pains.
You had your period and you passed a tissue that was clear and had veins it looked like why?
This actually is rather more common than you might think. When you have a period your body is shedding the uterine lining that its been building up for weeks in preparation of a pregnancy. When you fail to become pregnant that lining is no longer needed and so your uterus begins contracting (thus cramping and lower back pain associated with a period) to expel the lining from the uterus. Most of the time the lining breaks up before it ever leaves your body, but occasionally some part of the lining remain intact. There actually are photos on-line of women who have passed the entire lining intact. Be warned, the photo may be disturbing to some. http://images.google.com/imgres?imgurl=http://farm4.static.flickr.com/3521/3295381129_326c81f8c3.jpg&imgrefurl=http://www.flickr.com/photos/21069544%40N07/3295381129/&usg=__tHLL53xSry3GSUfDNLiCLvcKw6c=&h=375&w=500&sz=81&hl=en&start=4&um=1&tbnid=9OwhAsHgJKgxpM:&tbnh=98&tbnw=130&prev=/images%3Fq%3Duterine%2Blining%26hl%3Den%26rls%3Dcom.microsoft:en-us:IE-SearchBox%26rlz%3D1I7GFRC_en%26sa%3DN%26um%3D1
