An infusion pump is primarily designed to deliver medication directly into the circulatory system. This method ensures that the drugs are quickly and effectively distributed throughout the body, allowing for precise control of the dosage and flow rate. Medications administered via infusion pumps can include those used for pain management, chemotherapy, hydration, or antibiotic therapy, all of which require consistent and accurate delivery to achieve the desired therapeutic effect.

While the other options represent important body systems, they are not the primary target for the administration of medications through an infusion pump. For example, drugs may affect the brain if administered systemically, but the delivery occurs through the circulatory system first. Similarly, medications might impact the lungs if inhaled but are not directly administered to them via an infusion pump. The digestive system processes medications taken orally but is not involved in the function of an infusion pump, which bypasses this route entirely through intravenous delivery. Thus, the circulatory system is unequivocally the primary and correct answer.
