Question

Quizplus · Accepted Answer

Adequate brain development is critical in attaining the age of viability as it is necessary for regulating life-sustaining functions such as breathing and heart rate. While a weight of at least 5 pounds is generally considered a marker for viability, infants born weighing less have also survived with advanced medical interventions. Similarly, survival past 28 weeks is an indicator of increased likelihood of viability but brain development and overall health are more important factors. Functioning digestive and respiratory systems are also necessary for survival but are dependent on brain development.
