The uterus is structurally suited for gestation (the development of the fetus during pregnancy) in several ways:
1. **Muscular Wall**: The uterus has a thick muscular wall composed of smooth muscle tissue, known as the myometrium. This muscular structure allows the uterus to contract and expand during pregnancy, facilitating the accommodation and growth of the developing fetus. These contractions also play a crucial role during childbirth by aiding in the expulsion of the baby from the uterus.
2. **Endometrial Lining**: The inner lining of the uterus, called the endometrium, undergoes cyclic changes in response to hormonal fluctuations during the menstrual cycle. During pregnancy, the endometrium thickens and becomes highly vascularized to support implantation and nourishment of the embryo. This richly vascularized endometrial lining provides an ideal environment for the developing fetus, supplying oxygen and nutrients through the placenta
