Umbilical cord Umbilical cord. In placental mammals, the umbilical cord (also called the navel string, birth cord or funiculus umbilicalis) is a conduit between the developing embryo or fetus and the placenta.

- By 5 weeks, the embryo’s heart is tubular in shape and begins to beat. The connections between the pregnant woman and the embryo are developing to form the placenta. The placenta will nourish the embryo, then the fetus, for the remainder of its stay in the uterus.

- For the placenta of fruit, see placentation. The placenta (also known as afterbirth) is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply, fight against internal infection and produce hormones to support pregnancy.he placenta attaches to the wall of the uterus, and the baby's umbilical cord develops from the placenta.

placenta The embryo is joined to the placenta by the umbilical cord. The placenta has a maternal surface that adjoins the uterus and fetal plate to which the umbilical cord and its blood vessels are attached.

Placenta The placenta provides oxygen and nutrients to growing fetuses and removes waste products from the fetus's blood. The placenta attaches to the wall of the uterus, and the fetus's umbilical cord develops from the placenta. These organs connect the mother and the fetus. Placentas are a defining characteristic of placental mammals, but are also found in some non-mammals with varying levels of development.

Velamentous Cord Insertion Pregnancy Complication In a normal gestational sac, the umbilical cord is inserted into the middle of the placenta and entirely enclosed in the amniotic sac. In a velamentous insertion, the cord inserts itself into the amniotic membrane rather than in the placenta. The baby's blood vessels then stretch along the membrane between the insertion point and the placenta. Velamentous cord insertion can lead to serious pregnancy complications, such as vasa previa.

- The placenta is a fetomaternal organ. The fetal portion of the placenta is known as the villous chorion. The maternal portion is known as the decidua basalis. The two portions are held together by anchoring villi that are anchored to the decidua basalis by the cytotrophoblastic shell.

- 1 In placental mammals, the extraembryonic membranes form a placenta and umbilical cord, which connect the embryo to the mother's uterus in a more elaborate and efficient way. 2  The blood supply of the developing fetus is continuous with that of the placenta.3  The placenta extracts food and oxygen from the uterus. The yolk sac contains yolk — the sole source of food until hatching. 2  Yolk is a mixture of proteins and lipoproteins. 3  The chorion lines the inner surface of the shell (which is permeable to gases) and participates in the exchange of O 2 and CO 2 between the embryo and the outside air.

How Does Nutrition Get From the Placenta to the Fetus? The placenta contains a collection of thin tissues, known as the blood barrier, that permits some particles to flow between the bloodstream of the mother and fetus while restricting others. The placenta transfers oxygen and nutrients from the mother's blood to the placenta and transfers waste products from the placenta's blood to the mother's blood.

The Human Placenta: an overview and some highlights The Human Placenta: an overview and some highlights Oops. Wrong species. Placenta of Homo sapiens sapiens . The biochemical and physical duet of the mother and the fetus in the formation of the placenta is one of the most carefully orchestrated phenomena in fetal development. It represents the cooperation of two distinct individuals to form a single structure that protects one and enables the genes of the other to live on.

What is the umbilical cord? The umbilical cord carries oxygen and nutrients from the placenta into your baby’s bloodstream. These blood vessels are enclosed and protected by a sticky substance called Wharton's jelly, which itself is covered by a layer of membrane called the amnion.

Placenta Previa Placenta previa is a complication of pregnancy in which the placenta (the organ that joins the mother and fetus and transfers oxygen and nutrients to the fetus) is implanted either near to or overlying the outlet of the uterus (womb).

- pertaining to the umbilicus. umbilical cord the structure that connects the fetus and placenta; it is the lifeline of the fetus in the uterus throughout pregnancy. About 2 weeks after conception, the umbilical cord and the placenta are sufficiently developed to begin their functions.he part that is attached to the placenta, still in the uterus, is expelled with the placenta. The stump that remains attached to the baby's abdomen is about 2 inches (5 cm) long. After a few days it falls off naturally. Clamping the umbilical cord.

Placenta: How it works, what's normal The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it. In most pregnancies, the placenta attaches at the top or side of the uterus. Various factors can affect the health of the placenta during pregnancy, some modifiable and some not. For example: Maternal age.

Blood Circulation in the Fetus and Newborn The fetus is connected by the umbilical cord to the placenta, the organ that develops and implants in the mother's uterus during pregnancy. Through the blood vessels in the umbilical cord, the fetus receives all the necessary nutrition, oxygen, and life support from the mother through the placenta. Waste products and carbon dioxide from the fetus are sent back through the umbilical cord and placenta to the mother's circulation to be eliminated.
