Cervix Undergoes Massive Real‑time Remodeling During Labor
Your cervix has to open from less than a centimeter to 10 centimeters during labor. The cervix is made of dense collagen rich tissue that has to soften, thin out, and stretch. There are two things happening at once: dilation (the opening) and effacement (the thinning). This is one of the reasons labor takes hours. Your body is physically remodeling tissue in real time. By the time you start pushing, your cervix has already done one of the biggest structural transformations of birth.
