The ossa coxae (containing the ililum, ishium, and pubic bones) are not fused in a fetal skeleton like in an adult human.
the fetal bones are much more delicate than the adult
The fetal vertebrae are comparing with adult from the curvatures. Some of the curvatures are not seen until after birth.
In the fetal skeleton, the ossa coxae (hip bones) are not fully fused, and they consist of three separate bones: ilium, ischium, and pubis. In the adult skeleton, these three bones have fused together to form a single hip bone. Additionally, the acetabulum, the socket where the femur connects to the hip bone, is not fully developed in the fetal skeleton but is complete in the adult skeleton.
it is weaker
The human stomach is bigger than the fetal pig's. This of course is if the human is an adult human.
Some key characteristics of fetal pigs include their small size, lack of fur, closed eyes and ears, underdeveloped limbs, and presence of umbilical cord attached to the placenta. Fetal pigs also have a developing skeletal structure, digestive system, and circulatory system.
Fetal pigs are not as developed as an adult.
no
compare the relative lengths and paths of the uterine tubes of the fetal pig and in the human
Yes
Fetal hemoglobin has a pair of gamma-globin molecules in place of the typical beta-globins of adult hemoglobin
A fetal pig's lungs are similar to an adult's in the interior. The difference is that it is much smaller.
