Study Notes
Homeostasis
- A process essential for maintaining the stability of biological systems and the continuity of life.
- Involves adjusting to changing conditions and maintaining stable body functions.
- Described by Walter B. Cannon (1871-1945).
Environmental Adaptation
- Organisms live in varying environments (terrestrial and aquatic).
- Environments can range from moderate to extreme conditions.
- Organisms adapt by developing physical and physiological changes in their bodies.
Internal Environment
- Involves maintaining the internal environment within tolerable ranges for life.
- The body's internal environment includes fluids, tissues, organs, and systems.
- These components are interconnected and controlled by both endocrine and nervous systems, enabling coordinated functions.
Regulatory Functions
- Homeostasis involves regulatory functions such as osmoregulation, excretion, and thermoregulation.
- These processes maintain balance between the internal and external body environments.
Homeostasis
- Self-regulating process, crucial for maintaining stable biological systems and life.
- Walter B. Cannon (1871-1945), identified and described the concept of homeostasis.
- Organisms adapt to varying environments (terrestrial and aquatic) by developing physical and physiological changes.
- Homeostasis ensures the internal environment remains within tolerable ranges, even with external fluctuations.
- Internal environment includes fluids, tissues, organs, and systems, all interconnected.
- Both the endocrine and nervous systems are involved in regulating and coordinating functions for proper performance.
- Regulatory functions like osmoregulation, excretion, and thermoregulation maintain balance between the internal and external body environments.
