(I)GCSE Topic 3.11 Placenta



The role of the Placenta in the nutrition of the Developing Embryo =
- When the child is in the uterus, it cannot digest, breathe, excrete
- Child digests through placenta structure / Umbilical Cord
- Placenta, biologically grows out of the embryo - not the mother
- Blood vessel inside the placenta are the child's blood vessels including the arteries and veins
- Glucose, Amino Acids, Fats inside mothers blood vessels cross into child's blood - crossing at the placenta.

    I'm really impressed with the quality of your posts this term. The extra detail in the homework and the addition of the classwork to the blog really helps. Well done
