amniotic fluid, which is composed mostly of water, fetal skin cells, electrolytes, and chemicals produced by the lungs. this fluid is regulated by the baby's intake and output of the fluid, which is necessary for the baby's nourishment and development. also, before 36 weeks, the fluid is of similar composition to the baby's plasma, but after 36 weeks it is composed mostly of the baby's urine (the baby swallows or "inhales" the amniotic fluid, then excretes or "exhales" the fluid).

What is the fluid-filled sac surrounding the developing embryo or fetus?
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.
What is the envelope of thin tissue that surrounds the developing embryo called?
The envelope of thin tissue that surrounds the developing embryo is called the amniotic sac. It is filled with amniotic fluid, providing protection and cushioning for the developing fetus during pregnancy.
What three structures protect and nourish the developing embryo?
Placenta, amniotic fluid and umbilical cord.
What is designed to cushion the developing embryo and to help it maintain a constant temperature?
The amniotic fluid inside the amniotic sac is designed to cushion the developing embryo and help maintain a constant temperature by providing a stable environment for the fetus to grow and develop in the womb.
Which does not play a role in nourishing the developing embryo and fetus?
The lungs do not play a direct role in nourishing the developing embryo and fetus. The placenta, umbilical cord, and amniotic fluid play key roles in providing nutrition and oxygen to the developing baby during pregnancy.
What contain an egg cell food storage tissue and a sticky fluid?
The yolk of an egg cell contains food storage tissue, which provides nutrients for the developing embryo. The egg white, or albumen, contains a sticky fluid that helps cushion and protect the developing embryo.
What is the name of the fluid-filled bag of thin tissue that develops around the embryo?

What is the name for the protective structure that forms around an embryo?
Amniotic membrane or amniotic sac, containing the embryo and amniotic fluid.
How does the protein control the sex of a developing embryo?
Genes control the sex of a developing embryo.
Why the human embryo is suspended in a fluid inside the womb?
The fluid inside the womb provides protection and cushioning for the developing embryo. It helps to regulate temperature, prevents dehydration, and allows the embryo to move and develop properly. It also provides essential nutrients and oxygen to support growth and development.
