Which of the following mammalian features acts as a shock-absorber to the developing embryo?
Answer Details
The mammalian feature that acts as a shock-absorber to the developing embryo is the amniotic fluid. The amniotic fluid is a clear liquid that surrounds the developing embryo in the uterus of a pregnant mammal. The amniotic fluid serves several functions, one of which is to act as a cushion to protect the embryo from mechanical shock or injury. The fluid is contained within the amniotic sac, which is made up of two membranes called the amnion and the chorion. The amnion is the innermost membrane that directly surrounds the embryo, while the chorion is the outermost membrane that lines the inside of the uterus. Together, these membranes and the amniotic fluid create a protective environment for the developing embryo, allowing it to grow and develop in safety.
