Morphology
The phrase is directly compositional: 'vitelline' means yolk-related and 'circulation' means blood flow, so the meaning 'blood circulation involving the yolk/yolk sac' is predictable from the constituents. Although the term is technical and low-frequency, its sense follows regular biomedical word-formation patterns and would be inferable by a learner who knows both words.
Etymology
Vitelline circulation uses a clear image: vitelline refers to the 'yolk' and circulation means the 'flow' of blood. So the phrase names the blood flow between the 'yolk sac' and the embryo that carries 'food', which is why it means the system that supplies the early embryo.
