The Uterus.

because it allows the baby to pass
Arterial walls contain thick, muscular tissue to pump blood throughout the body. Veins have thinner walls.
Thick muscular walls refer to the robust layers of muscle tissue found in certain organs or structures, particularly in the heart and blood vessels. In the heart, for example, the thick muscular walls of the ventricles enable powerful contractions to pump blood effectively throughout the body. Similarly, in arteries, thick muscular walls help withstand high pressure and regulate blood flow. These walls are essential for maintaining proper function and supporting the organ's physiological roles.

The uterus is adapted for its job of nurturing a developing fetus by having thick muscular walls that can expand during pregnancy to accommodate the growing baby. It also has a lining that thickens and sheds monthly to support implantation of a fertilized egg. The cervix acts as a barrier to protect the uterus from infections.
In longitudinal section, the walls of the atria are thinner, and lined with pestinate muscles. The walls of the ventricles, meanwhile, are thick and muscular.
The uterus is designed to be muscular because it has to bear a lot of weight.
The "muscular neck" of the uterus is called the cervix.
Arteries have thick muscular walls to push your blood and spread out the pulse so it lowers its pressure. Your blood pressure is quite high when it leaves your heart and it comes in pulses. When it finishes going through your arteries and into your capillaries, your body wants it to go slow and be gentle. The muscles in your arteries change it to a smoother flow as they push it along.
