I THINK THAT A monotremes is the answer.
first
placenta
True
The placenta begins absorbing nutrients and oxygen from the mother's body during the second trimester of pregnancy. By this time, the placenta is fully developed and effectively facilitates the exchange of substances between the mother and the fetus. This process is crucial for the growth and development of the baby throughout the remainder of the pregnancy.
The Placenta uses a the process of diffusion to diffuse the nutrients from the mothers blood into the babies. Then the umbilical cord carries the nutrients to the baby to the Placenta. Answer is Placenta
The embryo gets nutrients from the mother during pregnancy through the placenta. The placenta is a temporary organ that develops in the uterus and allows for the exchange of nutrients, oxygen, and waste products between the mother and the fetus.
Fetuses receive nutrients from their mothers through the placenta, which forms a connection between the mother's bloodstream and the fetus. The mother's blood carries oxygen and nutrients, such as glucose and amino acids, which are then transferred across the placenta to the fetus. Waste products from the fetus, like carbon dioxide, are also removed through the placenta into the mother's bloodstream for excretion.
For Plato the answer is provide the fetus with oxygen and nutrients and eliminate carbon dioxide and other wastes from the fetus All the above
this is the function of the placenta, the mothers blood flows through capillaries that run very close to capillaries filled with the fetus' blood and the gases diffuse across due to the higher oxygen affinity of fetal haemoglobin.
Mammals, such as kittens, have a cord that connects them to the placenta. The placenta transfers food and oxygen to the baby while it is growing. That cord, the umbilical cord, goes from the placenta to the navel (or, on a cat, where the navel would be). Sometimes that cord can get wrapped around part of the body during birth.
A mammalian embryo gets oxygen and nutrients from it mother by means of the umbilical cord which extends the embryonic blood supply into the placenta embedded in the mothers womb. The blood supply in the placenta is close to that of the mother and oxygen and nutrients diffuse across from the mother to the baby. With egg laying animals the nutrients are supply to the embryo as the yolk part of the egg and oxygen is supplied by diffusion through the permeable shell and shell membrane
Once an egg is fertalized, it travels the length of the fallopian tube and implants in the lining of the uterus. There it devides and grows and receives oxygen and nutrients through the mothers blood. 1AnswerI believe it is the placenta. 2 Answeri believe that it is the umbilical cord, but i am not sure if its an organ at all 3
