umbilical arteries
Umbilical Cord
The placenta. Deoxygenated blood flows to the placenta where the carbon dioxide is removed and oxygen added. Oxygen rich blood returns to the fetus. Blood is carried to and from the fetus by the umbilical cord.
The placenta attaches to the child by three blood vessels that make up the umbilical cord. The umbilical cord has three blood vessels one for oxygen and nutrients from the placenta to the baby and two arteries carry deoxygenated fetal blood from the baby back to the placenta.
The structure of the placenta is directly related to its function of facilitating nutrient and gas exchange between the mother and fetus. The placenta is composed of villi, which are finger-like projections that increase the surface area for exchange. The villi are surrounded by maternal blood sinuses, allowing for the diffusion of oxygen and nutrients from the mother's blood to the fetal blood, and the removal of waste products from the fetal blood.
The exchange of gases between the blood of the mother and that of the fetus through the placenta. It may be one of three different types- anxaemic, acapnic, or anaesthetic.
There are two veins that carry oxygen they are the Pulmonary vein and the Umbilical vein:-)
The umbilical vein is a vein present only during fetal development that carries oxygenated blood from the placenta.
umbilical cord contains two arteries and one vein. umbilican vein carries pure blood to the fetal heart and umbilical arteries carry impure blood to the placenta of the mother.
Umbilical Cord
umbilical cord
The function of the umbilical vein is to deliver oxygenated blood from the placenta to the fetus. From the placenta, the umbilical vein courses through the liver via the ductus venosus (fetal shunt), connecting then to the inferior vena cava.
no
It nourishes the fetal pig.
The blood goes from the mother to the placenta where gas exchange occurs to the fetus. From the placenta the blood goes into the arterium and to the body of the fetus.
It has the same purpose as all other placental pregnancies, it carries nutrients to the fetus from the mother.
Oxygenation occurs in the placenta. After this blood then returns to the fetus via the umbilical vein.
Its a placentation abnormality .Placenta got a fetal site .Fetal site which has a central depression is circumvallate placenta
