Animal Physiology Fundamentals

How do animals breathe, digest, move, and sense the world around them? Understanding the intricate biological systems that sustain animal life is fundamental to the study of biology, veterinary science, and zoology. This course provides a clear, structured path to mastering the core principles of animal physiology, starting with foundational cellular concepts and moving through complex organ systems. You will gain a deep understanding of how different species adapt and survive in their environments. Through clear explanations and practical examples, you will learn to analyze physiological mechanisms and appreciate the evolutionary beauty of animal life. What you'll learn: Understand the foundational principles of homeostasis and cellular communication; Analyze the nervous and sensory systems that allow animals to interact with their environment; Explore the cardiovascular and respiratory mechanisms of oxygen transport and circulation; Study the digestive and metabolic processes that convert food into energy; Examine renal function, osmoregulation, and waste excretion across different species; Learn about endocrine control and how hormones regulate growth, reproduction, and stress. This course begins with essential terminology and basic chemical principles before guiding you step-by-step through each major physiological system. It is designed specifically for beginners, biology students, and curious learners with no prior advanced background in physiology.
