In twin to twin transfusion syndrome, the arterial blood from the donor twin flows into which vascular compartment of the recipient twin?

Explanation:
Twin-to-twin transfusion syndrome occurs when shared placental vessels create an abnormal inter-twin blood flow. The donor’s arterial blood is shunted across placental arteriovenous connections into the recipient’s venous system, increasing the recipient’s venous return and causing hypervolemia, while the donor becomes relatively hypovolemic. The lymphatic system and the capillary bed aren’t the primary pathways for this transfusion pattern, and arterial-to-arterial pathways don’t describe the main donor-to-recipient flow in TTTS.
