Key Concepts Covered

➡️ Homeostasis – The process by which organisms maintain internal stability despite external changes
➡️ Feedback loops – Mechanisms that control the body's internal environment through stimuli detection and response
➡️ Negative feedback – A process that counteracts deviation from a set point to keep variables within narrow limits
➡️ Set point – The target value or optimal point a organism aims to maintain
➡️ Receptors and effectors – Components that detect changes and enact responses to restore balance
