Basic Physiology Test Questions
Course Introduction
Basic Physiology introduces students to the fundamental principles governing the function of the human body. Focusing on major organ systems including the nervous, muscular, cardiovascular, respiratory, digestive, renal, and endocrine systems the course emphasizes the mechanisms that maintain homeostasis and support life. Students will explore cellular processes, integrative body responses, and adaptations to environmental and internal changes. Through lectures, laboratory activities, and problem-solving exercises, students gain a comprehensive understanding of physiological processes and their relevance to health and disease.
