Course Overview:
BIO-203 is an introductory undergraduate course designed for non-majors, exploring the fundamental principles of human biology through a conceptual, application-oriented lens. Drawing from the textbook *Biology of Humans: Concepts, Applications, and Issues* by Judith Goodenough, Betty McGuire, and Robert Wallace (6th Edition), the course emphasizes the relevance of biological concepts to everyday life, health decisions, societal issues, and environmental concerns. Students will examine the structure and function of the human body, genetic inheritance, evolutionary processes, and ecological interactions, with integrated discussions on topics like disease, biotechnology, and bioethics. The course combines lectures, discussions, case studies, and multimedia resources to foster critical thinking and scientific literacy. No prior biology coursework is required, though a basic understanding of high school science is recommended. Assessments include quizzes, exams, group projects, and reflective essays on real-world applications.
Course Structure:
The course is divided into 5 study periods, aligning with the textbook’s six major parts (units). Each period builds progressively, incorporating readings, lectures, and activities focused on the assigned content. Periods typically span 2-3 weeks, depending on the academic calendar, with opportunities for review and integration across topics.
– Period 1: Part I – The Organization of the Body (Chapters 1-4)
Introduction to human biology, including the characteristics of life, basic chemistry, cell structure and function, and body organization with homeostasis. Students explore foundational concepts like atoms, molecules, cells, tissues, organs, and systems, setting the stage for understanding human physiology.
– Period 2: Part II – Control and Coordination of the Body (Chapters 5-10)
Focus on systems that regulate and coordinate body functions, covering the skeletal and muscular systems, neurons and the nervous system, sensory systems, and the endocrine system. Topics include bone health, movement, brain function, senses, hormones, and related disorders like diabetes.
– Period 3: Part III – Maintenance of the Body (Chapters 11-16)
Examination of systems essential for internal balance and survival, including blood, cardiovascular and lymphatic systems, immune defenses, respiratory system, digestive system and nutrition, and urinary system. Discussions highlight cardiovascular disease, immunity, respiration, obesity, and waste elimination.
– Period 4: Part IV – Reproduction and Development (Chapters 17-18)
Coverage of human reproductive systems, fertilization, embryonic development, and lifespan changes. Key issues include sexually transmitted diseases, AIDS, contraception, pregnancy, aging, and developmental disorders like autism spectrum disorder.
– Period 5: Parts V and VI – Genetics, Biotechnology, and Inheritance; Evolution and Ecology (Chapters 19-24)
Integration of molecular biology with broader perspectives, including chromosomes, cell division, genetics, DNA, biotechnology (with topics like stem cells and cancer), evolution, ecology, environmental impacts, human populations, resources, and pollution. Emphasis on inheritance patterns, genetic technologies, evolutionary history, and sustainability challenges.
Learning Outcomes:
By the end of the course, students will be able to:
1. Describe the chemical, cellular, and organizational foundations of human life, and explain how homeostasis maintains bodily functions.
2. Analyze the structure, function, and interconnections of major human organ systems, including their roles in control, maintenance, reproduction, and response to environmental stressors.
3. Apply biological concepts to real-world health issues, such as diseases, nutrition, and aging, while evaluating bioethical dilemmas.
4. Explain genetic principles, inheritance patterns, and biotechnological applications, including their implications for medicine and society.
5. Evaluate human evolution, ecological relationships, and the impacts of population growth and pollution on global health and sustainability.
6. Critically assess scientific information from diverse sources, including the textbook’s special topics, to make informed decisions about personal and societal biological issues.
