Introduction
The third trimester is a period of development when the fetus slows in growth in length and begins to increase substantially in weight, this is also the time where Individual variations increase. Some fetal systems, such as the respiratory system, only now begin to mature just prior to birth.
Immune system, IgG to specific maternal antigens transferred passively across the placenta during the last trimester of pregnancy.
