Perinatal Period(Completely solved)
Gestational Period: Preterm correct answers < 37 weeks
Gestational Period: Term correct answers 37 - < 42 weeks
Gestational Period: Post-term gestation correct answers > 42 weeks
Neonatal Period correct answers First 28 days (4 weeks) of life + preterm time period
Perinatal Period correct answers After 28 weeks of gestation up to 28 days following birth
Ductus venosus: correct answers connects umbilical vein to inferior vena cava
allows oxygenated blood directly from mom to enter circulation (bypasses liver) via inferior
vena cava
Ductus arteriosus: correct answers a channel of communication between the main pulmonary
artery and the aorta
allows majority of blood which would enter pulmonary vasculature to bypass directly to the aorta
(so what about those lungs then?)
