A teratogen is an agent that causes an abnormality for the fetus during pregnancy
. Drinking alcohol during pregnancy causes Fetal Alcohol Syndrome.This is because the alcohol passes through the blood and get into the womb thereby reaches the fetus.
Alcohol disturbs the nutrition and oxygen delivery for the baby in the mother’s womb. The development of organs and tissues is also affected due to alcohol consumption. Alcohol also causes permanent brain damage in the baby. Hence alcohol is considered as a teratogen in fetal alcohol syndrome.
There are 4 main blood groups (types of blood) – A, B, AB and O. Blood group O is the most common blood group. Almost half of the UK population (48%) has blood group O.
