AP PSYCHOLOGY

Detailed explanation-1: –The amnion contains protective amniotic fluid that bathes a developing embryo.-The allantois collects nitrogenous wastes.-A yolk sac surrounds the remaining yolk, which provides nourishment.-Fertilization occurs in the upper third of the oviduct; cleavage begins as the embryo moves down this tube to the uterus.

Detailed explanation-2: -The amnion, a thin ectodermal membrane lined with mesoderm, grows to enclose the embryo like a balloon. It is filled with a clear fluid, which is generated from many sources, such as the fetal skin, the amnion itself, the fetal kidneys, and possibly the fetal vessels.

Detailed explanation-3: -The amnion is a membrane that closely covers the human and various other embryos when first formed. It fills with amniotic fluid, which causes the amnion to expand and become the amniotic sac that provides a protective environment for the developing embryo.

Detailed explanation-4: -Amniotic fluid is a water-like substance surrounding the fetus in your uterus. The fetus grows inside an amniotic sac filled with amniotic fluid during pregnancy. The amniotic sac forms around 12 days after you become pregnant.

Detailed explanation-5: -Amniotic sac. A thin-walled sac that surrounds the fetus during pregnancy. The sac is filled with liquid made by the fetus (amniotic fluid) and the membrane that covers the fetal side of the placenta (amnion). This protects the fetus from injury. it also helps to regulate the temperature of the fetus.
