The uterus is the internal female sexual organ necessary for bearing the fetus. It is a hollow organ consisting of smooth muscles and located in a small pelvis of a woman.
Looks like a healthy female womb as an inverted pear. In this organ, the upper part or the bottom, the middle part, or the body, and the lower part - the neck are distinguished. The place where the body of the uterus passes into the cervix is called the isthmus.
The uterus has anterior and posterior surfaces. The anterior one is located next to the bladder (it is also called the vesicle). The other wall - the posterior - is located closer to the rectum and is called intestinal. The opening of the main female genital organ is limited to the posterior and anterior lips.
The uterus is normally slightly tilted anteriorly, it is supported on both sides by ligaments that provide it with the desired range of motion and do not allow this organ to descend.
The uterus of a woman with a nullipar weighs about 50 g, giving birth to this parameter ranges from 80-100 grams. The width of the uterus is about 5 cm (at the widest part), and 7-8 cm in length. During the gestation, the uterus can stretch height up to 32 cm, and in width up to 20 cm.
How does the womb look like from the inside?
- The uterus is lined with an endometrium - the mucosa, in which many blood vessels are located. This shell is covered with a single-layer ciliate epithelium.
- The next layer of the uterus is the muscular membrane or myometrium , which forms the outer and inner longitudinal and middle circular layers. Muscle tissue provides the necessary uterine contractions. For example, due to this, there come monthly and the process of childbirth passes.
- The superficial layer of the uterus is a parameter, or a serous membrane .
Determination of the status of the uterus with ultrasound
When carrying out an ultrasound, the doctor can evaluate:
- The size of the uterus , which varies depending on the constitution of the woman, her age and anamnesis.
- The position of the uterus. On ultrasound, you can see how the position of the uterus looks in space. The uterus may be diverted anteriorly or posteriorly. Both provisions are considered a variant of the norm.
- The condition of the myometrium. A homogeneous state of a given layer without any formations is considered normal.
- The state of the endometrium. By its thickness, you can determine the phase of the menstrual cycle.
What does the uterus look like during pregnancy?
The appearance of the uterus during the period of bearing the child undergoes significant changes. First of all, this is due to the increase in its size. No other organ of the human body can be so stretched.
Because of the growth of the uterus, its position also changes. Her neck becomes long and dense. It acquires a cyanotic shade and closes. Sheika begins to soften closer to childbirth. During the same birth, the cervical canal opens up to 10 cm to ensure passage through the birth canal of the fetus.
How does a woman's uterus look after giving birth?
After the birth of the baby, the uterus undergoes changes that are opposite to those that occurred with it during pregnancy and childbirth. Immediately after birth, the uterus weighs about a kilogram, and its bottom is located near the navel. During the postpartum period (40 days), the uterus continues to contract until it becomes the same size.
The cervix closes by 10 days, and by 21 - the outer pharynx acquires a slit shape.
How does the uterus look after cleansing?
Sometimes, for curing various diseases or conducting a diagnosis of a woman, scraping of the uterine cavity is performed . This means removing the upper layer of the uterine mucosa.
After this procedure, the cervix remains open for a while, and the inner surface of the uterus has an erosive surface, which is the result of scraping, which, with time, like any wound, is tightened with a new tissue.
