The first cry of a newborn baby is called vagitus.
Importance of Vagitus
Vagitus is not just a sound; it's a critical physiological event. It signifies the baby's transition from being fully dependent on the mother and placenta for oxygen, to breathing independently. Here's why it's so crucial:
- Initiating Lung Function: The first cry helps to inflate the baby's lungs, which were previously filled with fluid. This is a vital step for effective gas exchange.
- Transition from Fetal Circulation: As the reference states, vagitus is "critical to initiate the successful transition from fetal circulation," allowing the baby to begin using its own lungs to breathe.
- Assessing Newborn Health: The strength and presence of vagitus are indicators of a newborn's overall health.
Key Aspects of Vagitus

Function | Facilitates the initiation of independent breathing by inflating the lungs |
Significance | Represents a critical transition from fetal to postnatal circulation. It's crucial for the baby's survival. |
Diagnostic Value | Health professionals use it as an initial indicator of the baby's wellbeing |
In Summary
The first cry, vagitus, is more than a simple sound. It marks the start of a baby's independent life and is a vital step in their physical transition. The successful initiation of this cry is a crucial part of ensuring a healthy start for the newborn.
