Health Sciences - Anatomy and Physiology
Question Bank
Course Introduction
Health Sciences - Anatomy and Physiology is a foundational course that explores the structure and function of the human body, examining how various organ systems interact to sustain life. Students will study the major anatomical features and physiological processes of key systems, including the skeletal, muscular, nervous, cardiovascular, respiratory, digestive, and reproductive systems. The course emphasizes the interrelationships between structure and function at both the microscopic and macroscopic levels, integrating concepts relevant to health, disease, and wellness. Practical laboratory components and case studies will reinforce understanding, preparing students for advanced studies and careers in healthcare and biomedical fields.
