The umbilical cord is a thin organ that connects the fetus to the placenta while in utero. The umbilical cord contains two arteries and a vein that facilitates oxygen and nutrient transport to the fetus. It also transports fetal waste back to the placenta to be filtered in the maternal circulation.

In both males and females, the urethra is the tube that connects the bladder to the urethral opening. Urine travels from the bladder to the urethra and then to the outside of the body via the urethral opening. In the male, semen also travels through the urethra.

A urinary tract infection (UTI) is an infection caused by bacteria that occurs in the urinary system (kidneys, ureters, bladder, and the urethra). Symptoms are often uncomfortable and can include pain or burning upon urination, fever, and fatigue.

The uterine glands are in the epithelial, glandular compartment of the endometrium, which is contiguous with the luminal epithelium. The glands synthesize and secrete most of the proteins and other components of uterine fluid (histotroph). Glandular secretions are necessary for embryo implantation and survival.

The uterine horns are the points where the fallopian tubes and uterus meet.

Uterine leiomyoma is a benign tumor that originates from the smooth muscle layer (myometrium) of the uterus. It is also known as a uterine fibroid. Fibroids are the most common benign tumors of the female genital tract. While fibroids can be asymptomatic, they can also cause irregular or heavy vaginal bleeding and other symptoms due to pressure on neighboring organs.

Uterine leiomyosarcoma is a rare but malignant tumor of the myometrium. This condition is independent of a uterine leiomyoma; the presence of uterine leiomyomas does not increase a woman's chance of developing uterine leiomyosarcoma.

The uterus, also known as the womb, is a muscular, pear-shaped organ located between a woman’s rectum and her bladder. During pregnancy, this is where the fetus develops. In women of child-bearing age, the inner layer of the uterus (endometrium) thickens in preparation for the implantation of a fertilized egg each month. If there is no fertilized egg, the endometrium is shed through the vagina. This process is called menstruation.
