pregnancy s/sx Increased ____ due to increased pressure of the uterus on the bladder

fatigue

pregnancy s/sx _____ due to increased progesterone and body's effort to support the pregnancy

premature = before ___ completed weeks of pregnancy

placenta

structure attached to walls of uterus that provides oxygen and nutrients to the developing fetus and removes waste products -- arises from umbilical cord

APGAR

test used to assess newborns right after borth that measures things like their general appearance, activity, breathing -- scoring ranges from 0-10 - 10 = perfectly healthy
