chorion

As nouns the difference between villus and chorion

is that villus is (biology) a small projection from a mucous membrane, particularly those found in the intestines while chorion is (anatomy|biology) the protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus.

As nouns the difference between villi and chorion

is that villi is (biology) while chorion is (anatomy|biology) the protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus.

As nouns the difference between chorion and trophoblast

is that chorion is (anatomy|biology) the protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus while trophoblast is (cytology) the membrane of cells that forms the wall of a blastocyst during early pregnancy, providing nutrients to the embryo and later developing into part of the placenta.

As nouns the difference between allantois and chorion

is that allantois is a sac, having a number of functions, that develops in the alimentary canal of the embryos of mammals, birds and reptiles while chorion is the protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus.

As nouns the difference between chlorion and chorion

is that chlorion is a chlorine ion while chorion is the protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus.

As nouns the difference between taxonomy and chorion

is that taxonomy is the science or the technique used to make a classification while chorion is the protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus.

As nouns the difference between chorion and chorionitis

is that chorion is the protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus while chorionitis is inflammation of the chorion.

As nouns the difference between chorion and chorioamnionitis

is that chorion is (anatomy|biology) the protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus while chorioamnionitis is inflammation of the fetal membranes (amnion and chorion) due to a bacterial infection, most often associated with prolonged labour.

As nouns the difference between chorion and chorioallantois

is that chorion is (anatomy|biology) the protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus while chorioallantois is (anatomy) the vascular extraembryonic membrane, formed by the fusion of the allantois and the chorion, that makes up the placenta in most mammals; the chorioallantoic membrane.
