100 Examples of sentences containing the common noun "yolk sac"

Definition

The term "Yolk Sac" refers to a membranous structure that is part of the early embryonic development in vertebrates, including birds and mammals. It serves as a source of nutrients for the developing embryo before the formation of the placenta or the absorption of nutrients from the egg in oviparous species. The yolk sac is filled with yolk, a nutrient-rich substance that nourishes the embryo during its early stages of development.

Synonyms

• Nutrient sac
• Embryonic sac
• Vitelline sac

Antonyms

• None (as "yolk sac" refers to a specific biological structure)
