The lower opening of the thorax is: formed by, "the twelfth thoracic vertebra behind," by the "eleventh." And twelfth ribs at the sides. And in front by the cartilages of the tenth, "ninth," eighth, and seventh ribs, which ascend on either side and "form an angle," the infrasternal angle/subcostal angle, into the apex of which the xiphoid process projects.
Pregnancy causes the angle——to increase from 68°——to 103°.
