Coordination and regulation of body activities in mammals is achieved by both nerves and hormones. Nerves are a part of the nervous system and work by sending electrical signals, or impulses, between the brain and other parts of the body. This allows for rapid communication and control of muscle movement, sensation, and other functions. Hormones, on the other hand, are chemical messengers produced by glands in the endocrine system. They are transported in the bloodstream and help to regulate processes such as growth, metabolism, and reproductive functions. Hormones act more slowly than nerves but can have long-lasting effects. Together, nerves and hormones work to maintain the balance and stability of the body, allowing it to respond to changes in the environment and carry out daily activities.
