child are playful and adult care about serious things for their life.
Children think in the short term and mostly about their own needs.
Adults think in the long term and how they can help others: be productive.
The fetal blood has a greater oxygen-carrying capacity than adult blood.
cause it just is different!(:
Hemoglobin F, also known as fetal hemoglobin is not found in adult blood.
FalseAdult hemoglobin has less affinity for oxygen than fetal hemogloblin. That is why, as an adult female's blood passes BY the placenta, the oxygen diffusses into the fetal blood. Likewise, adult blood, having explelled the carbon dioxide during exhalation, has less concentration of carbon-dioxide than the fetal blood, so it diffuses out of fetal blood into the adult blood. That way, the fetus doesn't need respiration as an oxygen source, nor as a way to rid of waste and carbon dioxide.

A fetal pig's lungs are similar to an adult's in the interior. The difference is that it is much smaller.
It is much less serious.
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.
the fetal bones are much more delicate than the adult
Fetal pigs are not as developed as an adult.
The fetal vertebrae are comparing with adult from the curvatures. Some of the curvatures are not seen until after birth.
One thymes and ones mus's Haha, actually, a fetal pig has a larger thymus than an adult pig. The thymus plays a large role in maturing lymphocytes (ie, it has has a large role in the immune system). The thymus is active in young children and eventually degrades as the animal gets older.
