Document Summary
Physiology = homeostasis; pathologies arise when homeostasis fails: many different types of diseases can push imbalance in homeostasis, we may feel dehydrated/ill due to viruses, antibodies, insulin-dependent diabetes. Internal and external changes contribute to maintaining homeostasis. Internal change (e. g. , dehydration, cold/hot temperature, hunger) results in loss of homeostasis: organism attempts to compensate. So how do we understand human physiology: 1. Apply an integrated approach the use of different methods to address the question a multi-disciplinary approach: spans cell biology, biochemistry, molecular biology, behavioural science etc, 2. Dependent on food intake: can you think of a non-testable version of this hypothesis, students feel more intoxicated when drinking on an empty stomach, very difficult to quantify feeling, too vague, 3. Experimental design, e. g choice of the correct system (i. e model) Test tube: advantages, cheap, fast, no infrastructure or ethical issues, disadvantages, circuit not intact, functional measurements are less direct, 2.
