Abstract
The survival of the neonates is dependent on the physiological characteristics that enable them to adapt themselves initially to the placenta and then to the extra uterine environment. Of all the pediatric patients, neonates exhibit the most distinguishing physiological features that ensure their rapid development. This chapter focuses on the physiological characteristics exhibited by the neonates in the intrauterine as well as the extra uterine environment.
