Neonatal Physiology

Neonatal physiology refers to the physical and biological functions of newborns, particularly in their first month of life. During this period, a baby undergoes significant changes as it adapts from the womb to the outside world. Key aspects include respiratory changes, where the newborn begins to breathe air; circulatory adjustments, including shifts in blood flow; and thermal regulation, as they learn to maintain body temperature. The newborn's organs are still maturing, which makes them vulnerable to conditions like infections. Understanding neonatal physiology helps healthcare providers ensure the health and well-being of infants during this critical stage.
