human body systems

What human body system affects almost every organ and cell in the body? The endocrine system. The endocrine system contains 9 major glands and organs that produce, store, and secrete hormones. Secreted hormones control everything from body temperature, heart rate, and blood pressure to reproduction, the sleep-wake cycle, and our reaction to stress. Hormones enter the blood system and are delivered to all parts of the body where cells with specific receptors take up the hormones they need and regulate cell function.
