Hormonal Regulation in Animals

Hormonal regulation in animals refers to the process by which hormones—chemical messengers produced by glands—control various physiological functions. These hormones are released into the bloodstream and travel to target organs, influencing processes like growth, metabolism, reproduction, and mood. For example, insulin helps regulate blood sugar levels, while adrenaline prepares the body for 'fight or flight' responses. Hormonal balance is crucial; too much or too little of a hormone can lead to health issues. This complex system allows animals to adapt to changes in their environment and maintain overall homeostasis.
