Physiology for Non-Majors Exam Practice Tests

Course Introduction

This course provides a comprehensive introduction to human physiology tailored for students who are not majoring in biological sciences. It explores the fundamental principles governing the function of the major organ systems, including the nervous, cardiovascular, respiratory, digestive, and endocrine systems. Emphasis is placed on understanding how these systems maintain homeostasis and respond to internal and external stimuli. Real-world applications and case studies help students appreciate the relevance of physiology to health, disease, and everyday life, making complex concepts accessible through practical examples and interactive discussions. No prior background in biology is required.
