Answer
Endocrine
Explanation
The endocrine system uses hormones as a primary means of communication. Hormones are chemical messengers that are secreted into the blood by endocrine glands and travel to target organs or cells to elicit specific responses. The other systems (Reproductive, Nervous, Cardiovascular) may interact with or be affected by hormones, but they do not primarily use hormones as their main means of communication.
