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).
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 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 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.
Placenta, amniotic fluid and umbilical cord.
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.
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.
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.
The fluid-filled bag of thin tissue that develops around the embryo is called the amniotic sac. It helps protect and cushion the developing embryo/fetus during pregnancy.
amniotic sac
Amniotic membrane or amniotic sac, containing the embryo and amniotic fluid.
Genes control the sex of a developing embryo.
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.
