what is the function of the uterine wall?

Uterine wall provides a favorable environment to the fertilized embryo to get attached and grow. The thick muscles of uterine wall protect the growing baby and push the baby out at the time of birth.

Three layers make up the wall of the uterus. The outer wall is the serosa which contains fibers to support the organ. Next is the myometrium. This layer contracts during a woman's period to force the inner-most layer, the endometrium, to be expelled in a bloody discharge through the vagina. Each month a new endometrium layer forms and thickens so that if the woman conceives a child, it can receive the fertilized egg which must implant in the endometrium to survive.
