The different blood types
In a nutshell, there are 4 different blood types that people can have: types A, B, AB, and O. Each of these blood types can be further distinguished as either Rh-positive or negative. Blood types are controlled by alleles for either A or B antigens. These antigens are sugars or proteins on the surfaces of cells that the body uses to distinguish itself from foreign materials. This is why people with blood type A cannot receive type B blood, and vice versa.
There is evidence that certain blood types can be more resistant or susceptible to different health conditions such as heart disease or infection. For example, people with A, B, and AB blood types are slightly more likely to develop coronary artery disease compared to those with type O blood. However, other factors like family history and diet play a bigger role.
