Flashcards
Homeostasis
Homeostasis
The ability of living organisms to maintain a stable internal environment, even when external conditions change.
Variables regulated by homeostasis
Variables regulated by homeostasis
Body temperature, fluid balance, and blood sugar levels are just a few examples of internal conditions that are carefully regulated by living organisms.
Optimal functioning in homeostasis
Optimal functioning in homeostasis
The state of optimal functioning for an organism, where all internal conditions are balanced and stable.
Study Notes
Homeostasis in Living Systems
- Homeostasis refers to the ability of an organism to maintain a stable internal environment despite changes in the external environment.
- It involves the regulation of various physiological variables to ensure optimal functioning.
Variables Regulated by Homeostasis
- Body temperature
- Blood sugar levels
- Blood pressure
- pH levels
- Oxygen levels
- Water balance
- Ion balance
Optimal Functioning Condition
- Homeostasis aims to maintain a state of optimal functioning, which is a condition where an organism's physiological processes are operating within a narrow range of values, allowing for optimal health and performance.
