Which body system is responsible for producing hormones?

• A. Nervous
• B. Endocrine
• C. Exocrine
• D. Respiratory

Answer: (B)

Hormones are chemical messengers released into the bloodstream to regulate many bodily functions. The endocrine system is made up of glands that synthesize and secrete these hormones directly into the blood, coordinating processes like growth, metabolism, and reproduction. In contrast, the nervous system uses neurons and neurotransmitters for rapid signaling and does not primarily produce circulating hormones. Exocrine glands release substances through ducts to surfaces (like enzymes in the digestive tract or sweat from the skin), not into the bloodstream. The respiratory system focuses on gas exchange and oxygen transport. So, the system responsible for producing hormones is the endocrine system.
