Does the embryo develops?
The embryo develops not in the wombYour species may vary. Mammalian embryos develop within the uterus of their mothers. Bird and reptile embryos develop inside eggs. Some oviparous embryos develop inside eggs inside their mothers. In some fish and seahorses, the eggs laid by the female, but carried by the males in a pouch and the embryos develop within him.
How do fetuses get nutrients from their mothers?
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.
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.
What provides food and oxygen for a developing embryo?
The placenta supplies nutrients and oxygen to the developing embryo through the mother's blood supply. This organ develops during pregnancy and ensures that the growing fetus receives the essential components it needs for proper growth and development.

Do tiger shark embryos fight?

Why doesn't a human embryon need a large yolk sac?
Yolks are required for embryos in eggs because it's their only source of sustenance for it's development until it hatches. Humans embryos are connected to their mother by an umbilical cord, which the fetuses use to get nutrients directly into their blood streams from the mothers blood.
What are embryo splitting?
The technique of embryo splitting involves removing an embryo. Individual cells from this embryo are removed and then placed into petri dishes that contain the correct nutrients and hormones for growth. Each of the removed cells now divides to form a new embryo. These embryos are then implanted into the uterus of surrogate mothers. These surrogate mothers will then give birth to identical young.
Why is there no large yolk in a mammal embryo?
Mammals do not have a large yolk in their embryos because they rely on obtaining nutrients through the placenta from the mother's blood supply. This allows for direct transfer of nutrients and oxygen from the mother to the developing embryo, rather than storing nutrients in a yolk sac like some other animals do.
Statistics about cloning?

Why do food cravings occur in expecting mothers?
Most of expecting mothers craving for food maybe she needs more nutrients for her baby.
Do fetuses need a mechanism for respiratory exchange?
yes they do.and this need is served by the PLACENTA-a vascular connection between the mother and the foetus,where oxygen diffuses from the mothers blood to that of foetus and CO2 DIFFUSES FRM FETUSE'S BLOOD 2 MOTHERS.BUT,THEIR BLOOD R NOT IN DIRECT CONTACT.
Which trimester does the placenta being to absorb nutrients and oxygen from the mothers body?
first
When a pregnant woman ingests toxins such as alcohol and nicotine the embryo is put at risk because these toxic can?
