Vedclass · Answer

(C) The human placenta is classified as follows:$1$. Hemochorial: The maternal blood comes in direct contact with the chorionic villi because the maternal endothelium,connective tissue,and uterine epithelium are eroded.$2$. Metadiscoidal: Initially,the villi are distributed over the entire surface of the blastocyst,but later they are restricted to a disc-shaped area.$3$. Deciduate: During parturition,a portion of the maternal uterine tissue (decidua) is shed along with the placenta.$4$. Chorionic: It is formed primarily by the chorionic villi.Therefore,the correct classification is Hemochorial,metadiscoidal,deciduate,and chorionic.
