Biology with Physiology Exam Materials

Course Introduction

Biology with Physiology is an interdisciplinary course designed to provide a comprehensive understanding of living organisms with a particular focus on physiological processes. Students explore the fundamental principles of biology, including cell structure, genetics, evolution, and ecology, while delving deeply into how organisms function at molecular, cellular, organ, and systemic levels. Key topics cover homeostasis, neural and hormonal regulation, respiration, circulation, digestion, and excretion. Through laboratory work, lectures, and collaborative projects, the course equips students with the analytical skills and scientific knowledge needed for advanced study or careers in biological and health sciences.
