Definition: The uterus, also referred to as the womb, is the hollow organ in the female reproductive system that retains a fetus during pregnancy.
The uterus performs multiple roles and plays a major role in fertility and childbearing. This organ is able to change in shape, as muscles loosen and tighten to make it Feasible to carry a fetus. During pregnancy, the uterus develops as well as the muscles become fuller and stretched, like a balloon.
With this capability to expand, the human body would be not able to tolerate the rapid development of a fetus.
The Layers of the Uterus
The uterus is a hollow organ Composed of 3 layers of tissue:
The Perimetrium: This is the outside layer of tissue which lines the exterior of the uterus.
The Myometrium: The middle layer of the uterus is primarily made up of smooth muscle.
The Endometrium: The inside layer of the uterus that is the coating that builds up over the course of a month and is shed each month if no pregnancy occurs. This shedding of the lining of the uterus is your menstrual period.
When pregnancy occurs, the endometrium provides nutrients into the fertilized egg, and supports the placenta. The muscle nature of the uterus enables it to expand to accommodate a growing fetus. During childbirth muscular contractions in the uterus help to push the baby from the human body.
During childbirth, the uterus contracts to help push the fetus from your system.
These contractions squeeze the fetus out of the uterus and to the vagina using a series of muscular movements. After the baby is born, the uterus continues to contract, which aids the manhood to return to its regular size and also assists in stopping bleeding that occurs in the uterus during the delivery.
The Uterus and Surgery
A hysterectomy is a surgery to remove the uterus and is normally done when the uterus is diseased (such as cancer) or if dysfunctional uterine bleeding (heavy periods, long periods that cause anemia) is unable to be treated with less invasive procedures.
A C-section is a surgery to remove a fetus from the uterus rather than delivering in the traditional way through the anus.
Also called: womb,
Examples: when pregnant, the uterus expands to many times its original size and returns to its normal size after childbirth.
