They are not compatable and there will be clumping and clotting.
The clumping of blood is known as coagulation. This is a natural process that helps prevent excessive bleeding when a blood vessel is injured.
The anti-clumping protein in blood type A is anti-B antibodies. These antibodies are produced by individuals with blood type A to protect against foreign blood cells that have B antigens. They help prevent clumping or agglutination when incompatible blood types are mixed.
Type 'O'
No although type O can donate to anyone the positive (plus) can not be put into a blood with negative. This would cause blood clumping and would be very bad.
its the bad blood which uw loose which should be sent out of the body...if this blood remains in ur body it myt occur in deseases
it occur due to mismatch of blood. if recipient is denoted wrong type of blood group for example if a recipient have blood group a if he or she have donated blood group b they the anti antigen A present in blood group b will destroy the blood group A this is called clumping of blood.
Clumping of red blood cells, known as agglutination, can be managed by identifying and treating the underlying cause, such as certain infections or autoimmune disorders. Maintaining hydration, proper blood flow, and using blood thinners if necessary can help prevent clumping. In severe cases, medical interventions like plasmapheresis may be needed to remove antibodies causing the clumping.
Agglutunation
blood type A
Blood clumping, or agglutination, occurs when blood cells clump together due to the presence of antibodies that react with antigens on the surface of the cells. This can happen during incompatible blood transfusions or in certain autoimmune diseases where the immune system mistakenly targets its own blood cells.
Clumping of red blood cells when mixed with antiserum is known as agglutination. This reaction occurs when the red blood cells contain antigens that agglutinate with antibodies present in the antiserum. Agglutination is commonly used in blood typing to determine an individual's blood type.
