Textbook Exam Questions
Course Introduction
Biomedical Sciences is an interdisciplinary field that explores the biological and physiological principles underlying human health and disease. This course provides a comprehensive foundation in core subjects such as cell biology, genetics, biochemistry, anatomy, pathology, microbiology, and pharmacology. Students will gain a thorough understanding of the mechanisms of disease, diagnostic techniques, and the scientific methods used in clinical and laboratory research. Emphasis is placed on developing analytical and problem-solving skills, as well as the ability to interpret scientific data, preparing students for advanced study or careers in healthcare, medical research, biotechnology, and related disciplines.
