Question

how are carbon dioxide and urea , excreted by the foetus , removed

Answer 1

Dear student.

The place of foetus development in the female body is uterus. Uterus walls are highly prepared to receive the developing embryo. After some days of fertilization, the placenta develops. Placenta is a special organ that develops between the uterus wall and the developing embryo during pregnancy. Placenta consists of blood vessels which transfer nutrients and gases like oxygen from mother’s blood to foetus and excretory material from foetus to mother.
