What is the primary function of amniotic fluid?

The primary function of amniotic fluid is to protect the embryo from jolts and knocks. This cushioning effect is crucial as it helps to absorb shocks and maintain a stable environment for the developing fetus. By surrounding the embryo, the amniotic fluid provides a buffer against physical impacts, which could potentially harm the developing structures and tissues.

Additionally, amniotic fluid plays important roles in enabling movement, which is essential for musculoskeletal development, and maintaining a constant temperature. While other functions, such as offering limited nutrient supply or assisting in waste management, do occur to some extent, the primary and most significant role of amniotic fluid centers around its protective qualities.
