प्रश्न
The circulatory system of the fetus and that of the mother are never connected directly. What are the advantages?
Advertisements
उत्तर
The separate circulatory system facilitates quick diffusion of nutrients, metabolic waste and respiratory gases between the foetus and the mother. Bacteria and other pathogens cannot pass from the mother to the foetus because they are filtered out by the placenta. Blood pressure changes in the maternal circulation also cannot affect the foetus which has delicate blood vessels.
