An artificial uterus, sometimes referred to as an 'exowomb', would have to provide nutrients and oxygen to nurture a fetus, as well as dispose of waste material.

Mesoderm extends to the midventral line for some distance behind the umbilical cord, and forms the lower part of the abdominal wall; it ends below in a prominent swelling, the cloacal tubercle, which after the separation of the rectum becomes the genital tubercle.
