Human Anatomy and Physiology
Mock Exam
Course Introduction
Human Anatomy and Physiology is a comprehensive course that explores the structure and function of the human body at both the microscopic and macroscopic levels. Students will study the major organ systems, including the skeletal, muscular, nervous, cardiovascular, respiratory, digestive, urinary, and endocrine systems, examining how these systems work individually and together to maintain homeostasis. Through a combination of lectures, laboratory work, and hands-on activities, the course emphasizes the interrelationship between anatomy (the body's structure) and physiology (its functions), laying a foundational understanding crucial for careers in health, science, and medical fields.
