Answer
The lungs may not be a priority for maturation in a fetus because other developmental processes are prioritized that are critical for survival at earlier stages of gestation.
Solution
a
Developmental Prioritization: The fetus prioritizes the development of organs and systems that are crucial for survival at the specific stages of gestation
b
Oxygen Supply: Before birth, the fetus receives oxygen through the placenta, not the lungs, making early lung development less critical
Key Concept
Developmental Prioritization in Fetal Growth
Explanation
In the womb, a fetus receives oxygen via the placenta, reducing the immediate need for fully developed lungs, thus other organs and systems are developed first that are essential for early survival.
