His functions are the defense to infections, gas exchange and distribution of nutrients To fulfill all these functions has different types of cells suspended in plasmaBlood composition

distribution of bloodThe distribution of blood types is not the same, depending on the area and ethnicity may have a higher concentration of some specificblood type O the most present

this blood type is extremely low in Latin America

The B type is present in approximately 16% of the population, mainly in Asia

the rarest blood type is AB, as it is only present in 4% of the world population.One blood type to unite us all

What is it?It is to change the structure of red blood cells. because all blood types have a basic structure of sugar, but above that base, the A and B have a different residue each (the fourth most common group, AB, has a mixture of both). That makes little difference if, for example, it is transfused type B blood to a person with type A, your immune system will recognize it as foreign and provoke a response that will endanger your life.

What is it?Esto no sucede con la sangre de tipo O, que solo tiene la estructura de azcar bsica, que comparte con los otros grupos, y por ese motivo es universal.

what is the progress?scientists in Canada has created an enzyme that brings the possibility of converting any blood type universal blood that can be used regardless of whether such is compatible with the patient.

the enzyme is called glycoside hydrolase which had extracted from pneumococcal bacteria that causes pneumonia or sinusitis.

the authors say will have to improve the enzyme, also while not in circulation use can be more expensive than normal transfucion
