Question

Quizplus · Accepted Answer

Infant kidneys are less able to conserve water compared to adults, making them more susceptible to dehydration. While adults may become dehydrated if they do not drink enough, they are generally better able to regulate their fluid levels than infants. Rapid growth and adult fluid intake do not fully explain the difference in susceptibility to dehydration between Michael and his son Sean. The underdevelopment of the infant thirst mechanism may play a role, but it is not as significant as the reduced ability of infant kidneys to conserve water.
