What is the function of the amniotic sac during pregnancy?

To assist with labor
To house the fetus and provide protection
To supply nutrients to the fetus
To facilitate fluid exchange

The correct answer is: To house the fetus and provide protection

The amniotic sac plays a crucial role during pregnancy by housing the fetus and providing a protective environment. This membrane surrounds the developing fetus and is filled with amniotic fluid, which serves several important functions. This fluid acts as a cushion, protecting the fetus from physical shocks and impacts. Additionally, it helps regulate temperature, ensuring a stable environment for fetal development. The sac also allows for fetal movement, which is essential for musculoskeletal development. While the other options mention various functions related to pregnancy, they do not accurately describe the primary role of the amniotic sac. For example, while it helps create an environment for nutrient exchange indirectly, the actual supply of nutrients comes from the placenta. Similarly, assisting with labor and facilitating fluid exchange are functions associated with other structures within the reproductive system. Thus, recognizing the importance of the amniotic sac in its role of housing and protecting the fetus is essential for understanding fetal development during pregnancy.
