Morphology
The meaning 'blood that flows through the veins' is directly and compositionally derived from combining 'venous' (associated with veins) with 'blood' (the bodily fluid). This adjective+noun pattern is literal and cross-linguistically common (e.g. Spanish 'sangre venosa'), so a learner who knows both constituents can readily infer the MWE's meaning.
Etymology
Venous blood literally names the blood in the body's veins. Veins are tubes that carry blood 'back to the heart', so this blood usually has less oxygen and more waste than the blood in arteries. That's why venous blood means the darker, returning blood with less oxygen.
