Body Fluids and the Human Circulatory System

How does the human body transport oxygen, nutrients, and waste to sustain life? Understanding the complex network of body fluids and the circulatory system is fundamental to biology and health sciences. This text-only course guides you through the mechanics of the heart, the pathways of blood vessels, and the vital functions of blood and lymph. You will build a solid foundation in cardiovascular physiology, starting from basic terminology and scaling up to systemic circulation. What you'll learn: - Learn the essential components and functions of blood, lymph, and other body fluids. - Understand the anatomy and mechanics of the human heart and the cardiac cycle. - Explore the physiological differences between open and closed circulatory systems. - Trace the pathways of pulmonary and systemic circulation throughout the body. - Analyze the regulatory mechanisms that maintain blood pressure and homeostasis. - Practice applying your knowledge of cardiovascular health through written scenarios. You will begin with foundational definitions of fluid types and cellular components before moving on to cardiac mechanics and regulation. This structured text format allows you to study at your own pace, with clear explanations and written exercises to solidify your understanding. This course is designed for beginners, students, and biology enthusiasts looking for a conceptual introduction with no prior medical background required.
