Morphology

type + O

The meaning is fully compositional: 'type' (a class or category) combined with 'O' (the specific blood-group label) yields the O blood type. A B1 learner who knows both constituents can infer this refers to the O blood group and its properties; the construction (type + label) is a straightforward, cross-linguistically common noun classification, so it is transparent.

Etymology

Type O comes from the German word 'ohne', which means 'without', and scientists used O to show blood that is without A and B markers. That's why type O is often a 'universal donor' for transfusions.
