The uterus is an organ of the female body with a slit-like cavity. Some women and girls do not know exactly where the uterus is. This organ is located in the pelvic area, between the rectum and the bladder. The uterus of a nulliparous woman is smaller in size, weighs about 50 g, is 7 cm long, 4 cm wide, the wall thickness is approximately 2.7 cm. The uterus of women who have given birth is slightly larger in parameters, on average 2 cm more than the above data. By weight, an organ that carried one or more children can reach 80-100 g.
Where is the uterus?
As mentioned above, the location of the uterus is next to the rectum and bladder. The organ has a shape resembling an inverted pear, that is, its wide part is turned up, and the narrow part is down. Its size and shape can differ dramatically in different periods of a woman's life. The greatest changes occur during pregnancy and in the postpartum period.
The structure of the uterus
Nature is very smart, she created the female reproductive organ soso that it can stretch significantly during gestation and return to normal after childbirth, decreasing almost to its original size. The walls of the uterus are very strong and elastic, they consist of muscle fibers located along and across the organ. Due to its properties, it can significantly stretch depending on the size of the fetus. If there is no pregnancy, the volume of the uterus is very small, but during pregnancy, as the term increases, the organ can withstand a placenta weighing 0.4 kg, up to 1-2 liters of amniotic fluid and a baby up to 5 kg.
Where is a woman's uterus and what does it consist of?
The uterus consists of three parts:
- necks;
- body;
- bottom.
The walls of the uterus are lined with three layers. This is:
- outer covering, or serous membrane - perimetry;
- middle layer - myometrium;
- the inner layer is the endometrium.
Endometrium is a mucous membrane that undergoes changes every month. It depends on the phase of the menstrual cycle. In the absence of pregnancy, the endometrium is rejected by the uterus and excreted along with the blood, at this moment menstruation occurs, which lasts from three to 6 days, depending on the physiology of the woman. They may be accompanied by weakness and pulling pains in the area where the uterus is located. If a woman becomes pregnant, the body begins to secrete hormones that prevent the separation of the endometrium from the walls of the uterus. This is necessary so that the fetal egg can attach to the wall of the uterus.and start your development. In the first weeks of pregnancy, it is from the endometrium that the embryo receives the necessary nutrition.
Myometrium is a muscular membrane, the main component of the walls of the uterus. The size of the organ during pregnancy changes due to this particular part of the shell. Myometrium is a collection of muscle fibers that increase due to the multiplication of myocytes (muscle cells), as a result, the uterus lengthens 10 times and thickens up to 4-5 cm. term, the walls of the uterus in thickness are only 0.5-1 cm.
Where is the cervix?
Did you know that the cervix can indicate the stage of the ovulation cycle. Where it is located is not so difficult to determine. This is the junction of the vagina and the body of the uterus. The cervix consists of supravaginal and vaginal parts. The lower end of the vaginal part ends with a hole, the edges of which make up the anterior and posterior lip. The body of the uterus in the section resembles a triangle, its truncated lower corner continues into the neck.
The inner canal of the cervix has glands that secrete vaginal mucus, the texture and color of which depend on the phase of the cycle, and are also an indicator of women's he alth. The cervix itself is located deep in the vagina, at a distance of approximately 7.5-15 cm, shaped like a donut with a small hole in the middle.
Now you know exactly where the uterus and cervix are.
