Test Bank for Anatomy and Physiology The Unity of Form and Function 16th Edition by Kenneth Questions with 100% Correct Answers | Verified | Latest Update 2025/2026 Graded A+. What does the study of disease processes aid in understanding? - Ans →Normal functions. What do Phase IV clinical drug trials involve? - Ans →Testing a drug only on the specific human population who have the condition that the drug is intended to treat. What is the result of negative feedback? - Ans →A response that opposes the original deviation from normal. Is blood clotting an example of positive feedback? - Ans →Yes, because the action of the effector enhances the stimulus. What is the purpose of daily thyroid hormone replacement medication? - Ans →To maintain normal thyroid hormone levels. What does stratified epithelial tissue provide? - Ans →Protection, but it does not transport substances between the internal and external environments. What is the function of sebaceous glands? - Ans →To lubricate the skin. Can enamel be regenerated? - Ans →No, enamel cannot be regenerated. How can motor nerve fibers in the skin regulate blood flow? - Ans →By affecting the diameter of cutaneous blood vessels. Are blood plasma and interstitial fluid separated from each other? - Ans →Yes, but there is communication and exchange between these fluids. What does physiology emphasize? - Ans →Cause-and-effect mechanisms. What is the study of how disease or injury alters physiological processes called? - Ans →Pathophysiology. What is the first step in the scientific method? - Ans →The formation of a hypothesis. Which phase of clinical trials maximizes the number of test participants? - Ans →Phase III clinical trials. What do Phase I clinical trials NOT involve? - Ans →Testing on the target human population. What is the term for measurements in an experiment where the subject's group status is unknown? - Ans →Blind measurement. What makes a hypothesis scientific? - Ans →It can be tested. What must a theory be based on to be considered scientific? - Ans →Reproducible data. What is the normal range of blood glucose concentration after fasting? - Ans →Approximately 70 to 99 mg/100 ml. What is the normal range of arterial blood pH? - Ans →7.35-7.45. In a feedback loop, what does the integrating center send information to? - Ans →The effector. What are the regulators of effectors in most feedback loops? - Ans →Hormones and nerve impulses. What are homeostatic regulatory mechanisms that are 'built-in' to the organs? - Ans →Intrinsic mechanisms. What type of homeostatic regulatory mechanisms are the endocrine and nervous systems considered? - Ans →Extrinsic mechanisms. When blood glucose levels rise, what role do pancreatic islets serve in the feedback loop? - Ans →They act as the integrating center. What detects a decrease in mean arterial pressure? - Ans →A sensor. What type of feedback occurs when platelets accumulate at a damaged vessel site? - Ans →Positive feedback. What is the role of platelets in the positive feedback mechanism during vessel damage? - Ans →They act as effectors. What is pathophysiology? - Ans →The study of how disease processes affect the function of the body. What is comparative physiology? - Ans →The study of the physiological differences and similarities among different species. What is anatomy? - Ans →The study of the structure of organisms and their parts. What is the scientific method? - Ans →A systematic approach to research and experimentation. What is the purpose of clinical trials? - Ans →To test the safety and efficacy of new drugs or treatments. What is the significance of reproducible data in scientific research? - Ans →It ensures that findings can be verified and are reliable. What is the role of a hypothesis in scientific research? - Ans →It provides a testable prediction that can be investigated. What term describes the concept of maintaining stable internal conditions despite external changes? - Ans →Homeostasis.
