First, the real spontaneous breathing of the neonatal respiratory system begins after birth. Neonatal respiration mainly depends on the rise and fall of septal muscle, showing abdominal breathing, shallow breathing and irregular rhythm, but the frequency is fast. Appearance features: birth weight over 2500 g, body length over 47 cm, ruddy skin, less fetal hair, whole body skin covered with fetal fat, and clear hair.

Second, the immune system can transmit immunoglobulin IgG and gamma globulin to the fetus through the placenta. The newborn has specific immunity to a variety of infectious diseases, but this passive immune antibody gradually decreases and finally disappears after birth.
