Verified step by step guidance

Understand the concept of fetal gas exchange: In a developing fetus, oxygen and carbon dioxide are exchanged between the mother and fetus through a specialized structure called the placenta. This is because the fetal lungs are not yet functional for gas exchange.

Recognize the role of the placenta: The placenta acts as the interface between the maternal and fetal circulatory systems. Oxygen from the mother's blood diffuses into the fetal blood, and carbon dioxide from the fetal blood diffuses into the mother's blood.

Eliminate incorrect options: The kidneys and liver are involved in filtration and metabolism, respectively, but they do not play a role in gas exchange. The lungs are responsible for gas exchange after birth, but they are non-functional in the fetus.

Focus on the correct answer: The placenta is the organ responsible for fetal gas exchange, ensuring the fetus receives oxygen and removes carbon dioxide.

Apply this knowledge to similar questions: When asked about fetal functions, remember that the placenta is central to nutrient delivery, waste removal, and gas exchange during pregnancy.
