type O
You could have but there would not necessarily be a connection.
myocardium of the heart
No. The heart sounds are caused by the closure of heart valves. The first heart sound is caused by the closure of the AV valves (tricuspid and mitral). The second heart sound is the result of the closure of the aortic and pulmonic valve after the completion of systole. Turbulence of blood flow through the aortic valve would cause a murmur (an abnormal heart sound) during systole.
Blood pressure would decrease
The deoxygenated blood and the oxygenated blood would mix.
Antigens are displayed on the surface of a macrophage after the digestion of a bacterium.
AB blood does not have any A or B antibodies. If it did, then the antibodies would bind to the A and B antigens found on its own blood cells and clot. A person with this blood type can still have antibodies (such as antibodies to the Rh factor). AB blood types are considered "universal acceptors" because they can take any blood type in a transfusion, provided the Rh factor is the same.
B+ here is a guide for you: type A - A antigens B antibodies; type B - B antigens A antibodies; Type AB - A&B antigens and no antibodies; type O - no antigens and A&B antibodies. for the rh you just have to add if it is + or -.
the antibodies in the serum of the recipient
Massive blood clotting due to the person's anti-B antibodies binding to the donated red blood cells and the donated blood's anti-A antibodies binding to the person's red blood cells. This often results in death.
No
no because the antibodies in type A blood differ from the ones in type B blood so it would recognize the different blood as a threat and eliminate it
AB blood has both A and B antigens on the cells and therefore if it had any anti-A or anti-B antibodies they would cause the blood to clott and so it has neither. This means that any type of blood can be given to this person, as they will not recognise any antigens on the blood as foreign because they don't have and antibodies. On the other hand they can only give blood to other people of ht ethe type AB. Type A blood has a antigens but not b antigens so it can have anti-b antibodies and b ype blood i the reverse. O type blood has no antigens and therfore both types of antibodies. So all three other types of blood have antibodies that will recognise one or both of the antibodies and cause clotting. For this reason AB type is nicknamed the "universal receiver", meaning they can take from anyone.
Because the blood cells from the O-group donor have no antigens which would react with the A-antibodies in the recipient.
It depends on what you mean by "blood". If you mean Red Blood Cells, it is due to somthing called antigens. Type O has IgM anti-A antibodies and anti-B antibodies in blood serum, and this would "attack" blood that had A or B antibodies. Since AB has both, it cannot donate to O, and O can only receive O. With regards to Blood Plasma however, AB can donate to any group, including O.
No...someone with a B blood type has anti-A antibodies so the A blood type in the AB blood would cause clotting.
Their children have a 50/50 chance of being Rh Positive. If they have an Rh negative first child, there will be no problems with the second child (with Rh groups).There might be a problem if the first child was Rh positive. It is quite likely that during the delivery the child's blood mixed with the mothers. The mother would then have began producing Rh positive antibodies. This means that if the second child is also Rh positive - the antibodies will 'attack' the fetus.
