Today I will explain to you what it means when yolk sac echo is seen inside the sac.

It is normal to see the yolk sac inside the sac. Only with the yolk sac can the embryo and fetal heart develop. After the yolk sac embryo develops body folds, the archenteron is clearly divided into the archenteron within the embryo and the yolk sac outside the embryo, which contains a large amount of yolk. The wall of the yolk sac is formed by the extraembryonic endoderm and extraembryonic mesoderm. A membrane sac rich in blood vessels located on the ventral side of the embryo and surrounding the yolk. The contracted part that communicates with the embryo's midgut is called the yolk sac stalk. The cyst wall is composed of an inner layer of extraembryonic endoderm and an outer layer of extraembryonic mesoderm. The eggs of reptiles and birds are rich in yolk, and the yolk sac is large, which has the function of storing, decomposing, absorbing and transporting nutrients.

As the embryo grows, the yolk is continuously consumed, the yolk sac gradually shrinks, and is eventually absorbed into the body and fused to form part of the small intestine. The eggs of lower mammals are rich in yolk and their yolk sacs are quite developed; the eggs of viviparous mammals are yolk-poor eggs, and their yolk sacs are small and contain no yolk. During a normal human pregnancy, the size of the yolk sac increases with the gestational age from 5 to 11 weeks, and shrinks until it disappears after 12 weeks of pregnancy.
