Why is Fetal Hemoglobin Essential for survival of Placental animals?
Circulation of blood inside a human fetus’ body is different than that of an adult. Describe one functional or structural difference between adult and fetal circulation (other than the size of the organs), and explain why it is important during development.
Explain why the normal heart and respiratory rates of neonates are so much higher than those of adults, even though adults are so much larger.
