umm embryo??
The fluid-filled sac surrounding the developing embryo or fetus is called the amniotic sac. It is filled with amniotic fluid that protects and cushions the fetus, helping to regulate its temperature and provide room for movement.
The extraembryonic membrane that forms a fluid-filled sac is the amnion. It helps protect and cushion the developing embryo by surrounding it with amniotic fluid.
It's a vacuole.
The amniotic sac is the membranous fluid filled bubble in which the developing foetus is suspended in utero.
A fluid-filled sac, such as a bursa or a synovial joint capsule, acts as a cushion to reduce friction between moving parts of the body. It helps to lubricate joints and facilitate smooth movement.
A closed sac with fluid in it
A fluid-filled sac that surrounds an embryo is called an amniotic sac. This sac contains amniotic fluid, which provides protection and cushioning for the developing embryo.
The inner most membrane is the fluid filled amniotic sac, next is the yolk sac, where the first blood cell originates. The allantois forms near the yolk sac, while the chorion surrounds all the other ones.
Amnion is the membrane that covers the embryo. Chorion is the membrane that covers the amnion, the yolk sac, and the allantois. The space delimited by the chorion and the amnion is called amniotic cavity and it is filled with aminiotic fluid. The amniotic cavity has the functions of preventing desiccation of the embryo and of protecting it against mechanical shocks.

The fetus is enclosed in the amniotic sac, which is a fluid-filled membrane that provides protection and cushioning during pregnancy.
