What do you call the blood-filled space within the placenta where gas exchange occurs?

• A. Intervillous space
• B. Spiral artery
• C. Uterine vein
• D. Uterine artery

Answer: (A)

The blood-filled space within the placenta where gas exchange occurs is referred to as the intervillous space. This space is essential for maternal-fetal exchange, as it contains maternal blood that bathes the chorionic villi, where oxygen and nutrients are transferred from the mother to the fetus. Simultaneously, carbon dioxide and waste products from the fetus pass into the maternal circulation. This efficient exchange is crucial for the developing fetus's growth and overall health. The intervillous space is surrounded by the syncytiotrophoblast, which facilitates the transfer of substances. The structure of the placenta and its vascularization through this space are vital components in ensuring proper oxygenation and nutrient supply to the fetus throughout pregnancy. Understanding the function and significance of the intervillous space is fundamental in the study of placental physiology and prenatal care.
