Biological regulation refers to the processes that control and maintain the functions of living organisms. This includes mechanisms that regulate growth, metabolism, and homeostasis, ensuring that cells and systems operate efficiently. Key components of biological regulation include hormones, enzymes, and feedback loops that respond to changes in the environment or internal conditions. In multicellular organisms, biological regulation is crucial for coordinating activities among different cells and tissues. For example, the endocrine system releases hormones like insulin to regulate blood sugar levels, while the nervous system uses electrical signals to control muscle movements. Together, these systems help maintain balance and support overall health.
