Explanation:
The endocrine system is a complex of glands that secrete <u>hormones</u> as a chemical messenger. These hormones carry information and instructions throughout the bloodstream from one part of the body to another. These hormones control many body functions such as respiration, sensory perception, metabolisms, growth, reproduction, the mood among others.
On the other hand, the nervous system is made up of neurons that communicate with each other to extend a message (from our own body or the outside) to the brain, for analysis and further decision of what to do with that information. A group of neurons, sensory neurons, respond to several stimuli such as touch, light, and sound to let the brain know about the surrounding environment. Another group of neurons, motor neurons, work inside the body and carry signals to active muscle or glands.
