Table 1-1 Anatomy is the study of structure while physiology is the study of what? - answerPhysiology is the study of function and how the body part does what it does Explain your understanding of homeostasis. Note the difference between the intracellular fluid (ICF) and extracellular fluid (ECF). In addition to blood plasma, what constitutes the ECF? - answerHomeostasis is the body's tendency to maintain a certain internal environment. The body's internal environment is extracellular fluid which contains blood plasma and interstitial fluid. extracellular fluid is everything inside the body but outside the cell. Intracellular fluid is fluid within the cells List 5 factors/homeostatic balances in the body need to be maintained within certain limits. Why must these factors be maintained? - answeroxygen lvls, glucose lvls, temperature, pH, salt and water. these factors must be maintained because our body can only function in a certain range. For each of the five factors you listed, mention one body systems involved with their homeostasis. - answeroxygen lvl- respiratory, glucose lvls- digestive, temperature- circulatory, pH- respiratory, salt and water- urinary
