Body Fluids and Circulation: Foundations of Human Physiology

Every living cell in the human body relies on a continuous supply of oxygen and nutrients to survive, while constantly needing to flush out metabolic waste. This vital transport network is driven entirely by our body fluids and circulatory system. In this text-only course, you will build a solid foundation in human cardiovascular physiology. You will learn how blood, lymph, and the heart function as an integrated transport system to maintain homeostasis, regulate temperature, and support overall health. What you'll learn: - Understand the composition of blood, including plasma, formed elements, and blood grouping systems. - Explain the anatomy of the human heart, blood vessels, and the mechanics of double circulation. - Explore the lymphatic system and its critical role in fluid balance and immune transport. - Analyze the cardiac cycle, blood pressure regulation, and the basics of electrocardiogram (ECG) readings. - Identify common circulatory disorders and the lifestyle factors that influence cardiovascular health. This course begins with key terminology and the fundamental components of body fluids before guiding you through cardiac mechanics and systemic circulation. This course is designed for beginning biology students, pre-health learners, or anyone curious about the inner workings of the human body. No prior medical or advanced science background is required.
