The uterine cavity (from Latin uterus - uterus) is the internal cavity of the female body, which is located in the pelvis. It is a narrow canal, about 8 cm long and 4 cm wide. Important processes associated with female reproduction occur in the uterine cavity. The uterus is an organ that bears the fetus inside itself and also secretes blood during menstruation. In addition, the uterine cavity is the place where a woman gives birth to her child.
The main condition for the normal functioning of the uterus is the presence of the required size and shape of the uterine cavity. The uterine cavity is measured in centimeters in length and width and has an oval shape. The length of the uterine cavity in a woman is 7-16 cm, width - 2.5-4.5 cm. The shape and size of the uterine cavity can change depending on the age of the woman, as well as under the influence of various factors, such as pregnancy, childbirth, cesarean section , artificial termination of pregnancy and other surgical interventions. Changes occurring in the uterine cavity are called parametritis or parametrisis.
The intrauterine cavity is covered with a mucous membrane called the endometrium. The endometrium consists of two layers - functional and basal. The basal layer is located at the bottom of the uterus and is responsible for the regeneration and restoration of the functional layer. The inner layer of the mucous membrane is called the muscularis propria. The two muscles of the myometrium form the outer muscular layer, the outer muscular layer, which makes up the main structure of the uterus. They are designed to ensure that the uterine wall retains its shape and does not rupture during childbirth and pregnancy. In addition to muscles, the uterine lining has blood vessels and nerves that ensure normal blood flow and nutrition to the organs inside the uterus. Inside this canal are the cervical canal of the cervix, the uterine cavity, its posterior angle, the cervical canal completely lined with mucus, and the connective tissue of the ligaments and their canal. For correct work, a woman must not only maintain personal hygiene, but also maintain the normal condition of the organ cavity, monitoring the condition of the mucous membrane and its layer
