Physiology is the study of how the human body functions, examining the interactions between organs, tissues, cells, and biological molecules. It explores processes such as circulation, respiration, digestion, and nervous system activity, focusing on how these systems maintain homeostasis. The course covers key concepts like cellular physiology, neurophysiology, cardiovascular dynamics, and endocrine regulation. It also delves into how the body responds to stress, exercise, and disease, integrating knowledge from anatomy, biochemistry, and molecular biology. Practical applications include laboratory experiments, case studies, and clinical correlations to understand dysfunctions and develop medical interventions. Physiology provides a foundation for careers in medicine, healthcare, research, and biotechnology.
