What are two characteristics of the fetal skeleton skull that differ from the adult skeleton?

Why is a transplant consisting of fetal tissue less likely to provoke an immune rejection response than tissue from an adult?
Fetal tissue has lower levels of antigens, which are markers that the immune system recognizes as foreign. This makes fetal tissue less likely to provoke an immune response compared to adult tissue, which has a higher amount of antigens. Fetal tissue also has a higher ability to induce immune tolerance.
Where is manubrium of the sternum to the acromion of the scapula?
The distance from the manubrium of the sternum to the acromion of the scapula is approximately 16-18 inches (40-45 cm) in an average adult. This measurement can vary based on individual anatomy and body proportions.
Which blood cells are elevated at birth but decrease to adult levels in the first year of life?

How does fetal circulation differ from the circulation pattern after birth?
In fetal circulation, the placenta provides oxygen and nutrients to the fetus, so the lungs are not used for oxygen exchange - instead, a bypass called the ductus arteriosus shunts blood away from the lungs. After birth, the lungs take over oxygen exchange, the ductus arteriosus closes, and the foramen ovale between the atria closes, redirecting blood flow through the heart to support pulmonary circulation.
