info_text = 'Blood groups \nThere are 4 main blood groups (types of blood) \
– A, B, AB and O. Your blood group is determined by the genes you \
inherit from your parents.\nEach group can be either RhD positive \
or RhD negative, which means in total there are 8 blood groups.\
\n\nAntibodies and antigens \nBlood is made up of \
red blood cells, white blood cells and platelets in a liquid called plasma. \
Your blood group is identified by antibodies and antigens in the blood.\
\nAntibodies are proteins found in plasma. They\'re part of your body\'s \
natural defences. They recognise foreign substances, \
such as germs, and alert your immune system, which \
destroys them.\nAntigens are protein molecules \
found on the surface of red blood cells.\
\n\nThe ABO system\nThere are 4 main blood groups \
defined by the ABO system:\n -blood group A – has A antigens \
on the red blood cells with anti-B antibodies in the plasma\n \
-blood group B – has B antigens with anti-A antibodies in the \
plasma\n -blood group O – has no antigens, but both anti-A and anti-B \
antibodies in the plasma\n -blood group AB – has both A and B \
antigens, but no antibodies.\
\n\nThe Rh system\nRed blood cells sometimes have \
another antigen, a protein known as the RhD antigen. If this is \
present, your blood group is RhD positive. If it\'s absent, your \
blood group is RhD negative.\n\nThis means you can be 1 of 8 blood \
groups:\n\n -A RhD positive (A+)\n\n -A RhD negative (A-)\n\n -B RhD \
positive (B+)\n\n -B RhD negative (B-)\n\n -O RhD positive (O+)\n\n -O \
RhD negative (O-)\n\n -AB RhD positive (AB+)\n\n -AB RhD negative (AB-)'
