The amniotic fluid also helps regulate temperature, provides lubrication for movement, and allows for fetal lung development by helping the lungs mature and providing a stable intrauterine environment. The umbilical cord connects the fetus to the placenta and provides nutrients and oxygen, while the neural tube is a structure that forms early in embryonic development and gives rise to the brain and spinal cord. The embryonic disk is a flattened, circular structure that forms during gastrulation and gives rise to the three germ layers, which in turn give rise to all the tissues and organs of the body.

Question 12

The ages of 29 and 30 are a turning point for men, because children conceived past these ages are at greater risk for:
