Attempt the Quiz - Neonatal Development

Here are a few simple Quiz questions that relate to Neonatal development from the practical.

 || Incorrect! This is the value for later postnatal 44-68 weeks. The neonatal human drug clearance rate is approximately 1/2 of the adult.
+{Which of the following cardiovascular changes occurs beginning in the neonatal period:
+|type="[]"}
++ &nbsp; umbilical blood vessel cavity is lost
+|| postnatally over the course of weeks to months after birth. The adult anatomical remnant of the umbilical vein between the umbilicus and liver is the ligamentum teres.
++ &nbsp; foramen ovale closure
+|| foramen ovale closes by two separate forms; functional and structural. Functional closure begins at the first breath and is rapid. Structural (anatomical) closure is much slower and generally occurs before the end of the first year.
++ &nbsp; ductus arteriosus closure
+|| the ductus arteriosus is a direct connection between the pulmonary trunk and the dorsal aorta. Postnatal closure occurs initially by by smooth muscle contraction and begins at the first breath and is rapid, completed within the first day (about 15 hr after birth). Anatomical closure is much slower occuring by 2–3 weeks after birth (33% of infants), by 2 months (90% of infants) and by 1 year (99% of infants). The adult anatomical remnant of the ductus arteriosus is the ligamentum arteriosum.
++ &nbsp; ductus venosus closure
+|| the ductus venosus connects portal and umbilical blood to the inferior vena cava. Functional closure occurs postnatally within hours. Structural closure commences days after birth and completes by 18 to 20 days. The adult anatomical remnant of the ductus venosus is the ligamentum venosum (a dorsal fissure on the liver).
