Minus stations superior to that an plus stations inferior to that.

52
Q

Passageway

A

Birth canal: composed of bony pelvis, cervix, pelvic floor, vagina, and introitus. Size and shape of bony pelvis must allow baby to pass through and cervix must dilate in response to contractions and fetal descent.
