Living organisms achieve control and coordination through the nervous and endocrine systems. The nervous system uses electrical impulses to transmit rapid signals, enabling swift responses to stimuli. It includes the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves and ganglia). The endocrine system, comprising glands that release hormones, regulates slower, but long-lasting, processes. Together, these systems integrate sensory input, process information, and coordinate effector organs like muscles and glands to maintain homeostasis. This dual control mechanism allows organisms to respond rapidly to immediate threats and regulate long-term physiological functions for overall coordination.
