Course Introduction
Biomedical Sciences is an interdisciplinary field that explores the biological and physiological principles underlying human health and disease. The course covers foundational topics such as human anatomy and physiology, cell biology, genetics, biochemistry, microbiology, immunology, and pathology. Students gain an understanding of how the human body functions at the molecular, cellular, and systemic levels, and how abnormalities in these processes lead to disease. Emphasis is placed on scientific research methods, laboratory skills, and the application of biomedical knowledge in clinical, diagnostic, and therapeutic contexts. The course prepares students for careers in healthcare, research, and biotechnology, as well as for further study in medicine or allied health professions.
