Introduction
The uterus is shaped like an inverted pear, wider at the top and narrower at the bottom, flattened anteriorly and slightly convex posteriorly. Under normal circumstances, it is held in position by ligaments and pelvic floor muscles. The upper, wider portion is called the body of the uterus, the uppermost part is referred to as the fundus, and the lower narrow cylindrical portion is the cervix. The uterine wall consists of three layers of tissue: the outer serous layer, the middle muscular layer, and the inner mucosal layer, known as the endometrium.

The uterus is located in the center of the female pelvic cavity, between the bladder and the rectum. A detailed analysis is as follows:

This organ is shaped like an inverted pear, wider at the top and narrower at the bottom, flat on the front and slightly convex at the back. Under normal circumstances, it remains fixed in position by ligaments and pelvic floor muscles. The wider upper portion is called the body of the uterus, the uppermost part is referred to as the fundus, and the lower, narrow, cylindrical part is the cervix. The uterine wall consists of three layers of tissue: the outer serous layer, the middle muscular layer, and the inner mucous layer, known as the endometrium.

The cervix opens into the vagina, and the uterine cavity communicates with the vagina through the cervical canal. After puberty, the endometrium undergoes periodic shedding and bleeding in response to cyclic changes in ovarian hormones, forming menstruation. During pregnancy, the uterus serves as the site for embryonic implantation and fetal development. During childbirth, contractions of the uterine muscular layer assist in the delivery of the fetus and associated tissues.

It is important to maintain uterine health in daily life, undergo regular gynecological examinations, maintain good lifestyle habits, avoid prolonged sitting, and pay attention to personal hygiene.
