Chapter 16, Problem 12MC
Summary Introduction
Introduction:
The baby moves inside the uterus as it grows. After 34 weeks, the baby generally comes into a vertex or head-first presentation, in which the head of the baby comes out first during the delivery. In the non-vertex position, other parts of the body come first. This creates complications during the delivery.
