SPECIFIC EXPECTATIONS
By the end of this course, students will:
e1.1 analyse the social or economic impact of a medical device or technology related to the treatment of the human circulatory, respiratory, or digestive system (e.g., a pacemaker, a heart- lung bypass machine, kidney dialysis) [AI, C]
Sample issue: A reliable blood substitute for use during emergencies or blood shortages could save many lives and create huge revenues for its producers. However, clinical trials have shown that patients receiving artificial blood have a significantly higher risk of heart attack than those receiving donated blood, thus in- creasing medical costs.
Sample questions: Are the costs of the dispos- able capsules used for capsule endoscopy worth the benefits of detecting gastrointestinal diseases? Why or why not? What social and economic issues arise from the use of respir- ators to keep gravely injured or terminally ill patients alive?
e1.2 analyse the impact of various lifestyle choices on human health and body systems (e.g., the impact of excessive alcohol consumption on the liver; of smoking on the respiratory system; of loud noise on the auditory system)
Sample issue: The importance of a sensible diet and regular exercise in maintaining healthy body weight is well known. Yet the popularity of fast food and computer games means that many young people are eating too much fat and are not getting enough physical activity. Consequently, childhood obesity levels are on the rise in Canada.
Sample questions: Does information in the media have an impact on your personal lifestyle choices? Why or why not? Why is it important to limit strenuous outdoor activity on smog days or during heat alerts? What are the dangers of eating undercooked hamburgers?
By the end of this course, students will:
e2.1 use appropriate terminology related to animal anatomy, including, but not limited to: systolic contraction, diastolic pressure, diffusion gradient, inhalation, exhalation, coronary, cardiac, ulcer, asthma, and constipation [C]
e2.2 use medical equipment (e.g., a stethoscope, a sphygmomanometer) to monitor a human system, and interpret the data collected [PR, AI]
