Embryo excretes nitrogenous wastes into it?
Embryos do not excrete nitrogenous wastes into the environment but rather rely on the mother's body to remove these wastes through the placenta. The mother's kidneys process the nitrogenous wastes from the embryo's blood and excrete them into her own bloodstream for elimination.
How are nutrients and wastes passed between the mother and baby?
Through the umbilical cord and the placenta.
How does the structure of the placenta prevent the mothers blood from mixing with the blood of the developing embryo?
The structure of the placenta includes fetal capillaries and maternal blood spaces separated by a thin membrane. This membrane allows for the exchange of nutrients and wastes between the mother and the developing embryo without their blood mixing. The exchange occurs through diffusion and active transport mechanisms.
Organ through which an embryo receives nourishment and gets rid of wastes?
Placenta
What Substances is not reabsorbed by blood after it passes through the kidneys?
wastes
How do embryos receive oxygen and nutrients and how does it get rid of wastes?
Embryos receive oxygen and nutrients through the mother's placenta, which acts as a filter to supply essential substances. Waste products, such as carbon dioxide and urea, are also removed by the placenta and then excreted from the mother's body. This exchange of materials occurs through the blood vessels of the mother and the embryo.
What supplies food and oxygen for the developing embryo?
The developing embryo is nourished by the yolk sack until implantation. Upon implantation the placenta begins to develop, the placenta acts as the fetal lung , it transports oxygen to the fetus and carbon dioxide away from the fetus via the umbilical cord. The placenta also provides stored carbs for the developing fetus.
Describe how the embryo receives oxygen and nutrients and how it gets rid of wastes?
its gets it all through the umbilical cord
What differences in fetal elimination of nitrogenous wastes account for the structural differences beteen pigs and humans?
There isn't a difference in fetal elimination of nitrogenous wastes between a pig and a human. Both send the waste back to the mother through the umbilical cord where the mother excretes the waste.
What differences in fetal elimination of nitrogenous wastes account in a pig?
Humans and pigs both use the umbilical cord for fetal elimination of nitrogenous wastes. Both send the waste back to the mother through the umbilical cord and then the mother excretes the waste.
How does a fetal pig eliminate metabolic wastes?
As in any other mammalian species, the pig eliminates wastes through the umbilical cord, and then the mother's vascular system moves it back into her bloodstream. From there it is metabolized in her liver/kidneys. It all happens through the bloodstream until the pig is born and his own digestive system and kidneys kick in.
Where are nutrients absorbed into the blood through the walls of?
It passes through the wall of the digestive system, then into the blood.
