Their size and hydrophobicity enable their passage through the placenta and blood-brain barrier and into the gastrointestinal tract and lungs, potential sites for harm to occur . Wikipedia Answer: Placenta is a disc like structure that forms a connection between the embryo and the uterine wall. It consists of three parts: the integument, forming its outer layer, the nucellus (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center.The female gametophyte specifically termed a megagametophyte is also called the Placental hormones are required for the establishment and maintenance of pregnancy, adaptation of the maternal organism to pregnancy and fetal growth.

Placenta helps in the nutrition of the embryo as the nutrients like amino acids, monosugars, vitamins, etc., pass from the maternal blood into foetal blood through placenta. The corpus luteum doesnt get enough credit for the important role it plays in the menstrual cycle and pregnancy. Neutrophils circulate in the blood, but enter different parts of the body where an invader has been identified. Parts In a pregnant female, the umbilical cord joins the embryo to the placenta. Externally, some parts of a seed are obvious. The human placenta is characterized by the intensity of the trophoblast invasion into the uterus wall and the specificity of its hormonal functions. Placenta accreta: placenta accreta is placenta previa in the presence of a uterine scar.
