What is the main role of the placenta in fetal life?
Providing a constant supply of glucose to the fetus
What happens to the infant immediately after birth?
The infant's hormonal and metabolic systems adapt to extrauterine life
What is the significance of glucose in the newborn?
It is a primary metabolite for the fetus and newborn
What is the result of the infant's adaptation to extrauterine life?
Regulation of glucose levels and adaptation to extrauterine life
What is being measured when evaluating an infant's glucose levels?
Serum glucose value
Study Notes
Disorders of Glucose Homeostasis in Neonates
- Glucose is the primary metabolite for the fetus and newborn during intrauterine life.
- The fetus relies on the placenta for a constant supply of glucose during intrauterine life.
- At birth, the infant is abruptly removed from the placental environment, triggering hormonal and metabolic changes.
- These changes facilitate adaptation to extrauterine life and regulate glucose levels.
- A serum glucose value is a crucial indicator of glucose homeostasis in neonates.

This quiz covers the importance of glucose homeostasis in neonates, specifically in infants of diabetic mothers, and the risks of neonatal hypoglycemia. Learn about the fetal reliance on the placenta and the abrupt changes at birth.
