What is the ropelike structure that connects the embryo and the mothers placenta?
Or eat? From mom, of course. Shown is a detailed representation of the placenta. And this is where all these interactions occur. The fetus could not grow and develop without oxygen and nutrients from the mother. Wastes from the fetus
must also be removed in order for it to survive. The exchange of these substances between the mother and fetus occurs through the placenta. PlacentaThe placenta is a temporary organ that begins to form from the trophoblast layer of cells shortly after implantation. The placenta continues to develop and grow to meet the needs of the growing fetus. A fully developed placenta is made up of a large mass of blood vessels from both the mother and fetus. The maternal and fetal vessels are close together but separated by tiny spaces. This allows the mother’s and fetus’s blood to exchange substances across their capillary walls without the blood actually mixing. The fetus is connected to the placenta through the umbilical cord, a tube that contains two arteries and a vein. Blood from the fetus enters the placenta through the umbilical arteries, exchanges gases and other substances with the mother’s blood, and travels back to the fetus through the umbilical vein. The fetus and the placenta. Notice the fetus is attached to the placenta by the umbilical cord, made of two arteries and one vein. Amniotic Sac and FluidAttached to the placenta is the amniotic sac, an enclosed membrane that surrounds and protects the fetus. It contains amniotic fluid, which consists of water and dissolved substances. The fluid allows the fetus to move freely until it grows to fill most of the available space. The fluid also cushions the fetus and helps protect it from injury. Summary
Review
What connects the mother to the placenta?The placenta is connected to the baby by the umbilical cord and to the mother through her inner uterine wall. The umbilical cord contains three blood vessels: two arteries and one vein.
What is the thick blood rich tissue that lines the walls of the uterus during pregnancy and nourishes the embryo?The placenta (pluh-SEN-tuh) is a thick, blood-rich tissue that lines the walls of the uterus during pregnancy and nourishes the embryo. Although the blood supply of the mother and the developing embryo are kept separate, materials diffuse from one blood supply to the other through the umbilical cord.
How is placenta connected to the embryo?Your baby is connected to the placenta by the umbilical cord.
What is the name of the structure that attaches the placenta to the developing baby?The umbilical cord connects the placenta to your baby. Blood from the mother passes through the placenta, filtering oxygen, glucose and other nutrients to your baby via the umbilical cord.
