Physiological refers to the normal functions and processes of living organisms, including humans, animals, and plants. It involves how the body’s systems, organs, tissues, and cells work together to sustain life.
Key Aspects of Physiology
✔ Bodily Functions – Covers breathing, digestion, circulation, nerve signaling, and more.
✔ Homeostasis – The body’s ability to maintain stable internal conditions (e.g., temperature, blood pressure).
✔ Cellular & Organ System Interactions – Explains how different body parts work together.
Examples of Physiological Processes
| System | Physiological Function | Example |
|---|---|---|
| Respiratory System | Oxygen intake & carbon dioxide removal | Breathing & lung function |
| Circulatory System | Blood flow & oxygen delivery | Heart pumping blood |
| Digestive System | Food breakdown & nutrient absorption | Stomach digesting food |
| Nervous System | Sending & receiving signals | Reflexes & memory formation |
| Endocrine System | Hormone production & regulation | Insulin controlling blood sugar |
| Muscular System | Movement & posture control | Running, lifting, stretching |
Physiological vs. Psychological
| Term | Definition | Example |
|---|---|---|
| Physiological | Related to bodily functions & physical processes | Heartbeat, sweating, digestion |
| Psychological | Related to mental and emotional processes | Thinking, stress, emotions |
Why Is Physiology Important?
✔ Explains How the Body Works – Helps understand normal and abnormal functions.
✔ Essential for Medicine – Guides treatments for diseases, injuries, and health conditions.
✔ Optimizes Human Performance – Used in sports, fitness, and rehabilitation.
Conclusion
Physiological processes are the core functions of life, enabling organisms to breathe, digest, move, and maintain balance. Studying physiology helps us understand health, disease, and human performance.
