What is the name of the sac that cushions and protects a developing embryo and fetus?

• A. Amniotic Material
• B. Amniotic Sac
• C. Placental Sac
• D. Fetal Membrane

Answer: (B)

The amniotic sac is a vital structure during pregnancy, serving as a protective and supportive environment for the developing embryo and fetus. This sac is filled with amniotic fluid, which cushions the fetus against physical shocks, helps maintain a constant temperature, and allows for free movement, which is important for musculoskeletal development. Additionally, the fluid serves to protect the fetus from infections and allows for the exchange of nutrients, electrolytes, and water.

The amniotic sac is formed from membranes that arise from the fertilized egg and is an essential part of the amniotic cavity, which is crucial for the proper development of the fetus throughout gestation. By providing physical and environmental protection, the amniotic sac plays an indispensable role in ensuring the health and safety of the developing baby.
