Fetal development and birth


When the sperm cell attaches to the egg cell, fertilization occurs. Once

fertilization occurs this makes the egg cell differentiate into a small ball of

cells referred to as the embryo. As the embryo grows and gets larger it is

referred to as a fetus until the baby is born. While the fetus is in the womb, it

 is totally reliant on the mother. The mother provides oxygen as well as

nutrients such as food and water.

 

The placenta


The placenta is a small organ attached to the uterus. It acts as a transfer unit

between the mother and baby. As the mothers blood and the fetus blood does

not mix, the placenta lets nutrients reach the fetus and waste products reach

the mother.
