What is the difference between amnion and chorion?
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.
What is a fetus surrounded by?

What fluid is in the amniotic sac?
The amniotic sac contains a fluid known as amniotic fluid that is composed of amnion and water after fertilization. About ten weeks later the liquid contains proteins, carbohydrates, lipids and phospholipids, urea and electrolytes, all of which aid in the growth of the fetus. In the latter stages of development the fluid will also contain fetal urine.
Which animal lacks an amnion?
Amnions surround embryos by encasing them in amniotic fluid. Frogs are animals that lack amnions. Only reptiles and mammals have amnions.
What is the water sac in a pregnant woman called?
