7.3.0. PLACENTA: INTRODUCTION
The placental structure is formed upon the nidation of the of the blastocyst in the endometrium of the uterus, 27-28 days after fertilization of the oocyte. The blastocyts gives rise to two layers of trophoblast: cytotrophoblast and syncytiotrophoblasts.
The placenta contains numerous lobules consisting of primary, secondary and teriary stem villi arosen from the chrionic plate. The terminal villus is the functional unit of the placenta and consists of an inner layer of cytotrophoblasts and an outer layer of syncytiotrophoblasts. The villous stroma contains loose mesenchyme cells and macrophages (Hofbauaer cells). A villous capillary network is present.
All structures, including macroscopy and cell types are present in our POJA- collection.
