Foundations of the Circulatory System

The circulatory system is the vital transport network that keeps complex organisms alive. This course provides a clear, written guide to its intricate workings, helping you build a solid understanding of how life is sustained at a cellular level. Upon completing this course, you will have a foundational knowledge of cardiovascular biology. You'll be able to explain the journey of blood through the body, describe the roles of key organs and tissues, and compare the different strategies that have evolved for circulation in the natural world. What you'll learn: * Understand the core functions of the circulatory system, including nutrient delivery and waste removal. * Learn the detailed anatomy of the human heart and the mechanics of the cardiac cycle. * Distinguish between arteries, veins, and capillaries and their specific roles in blood transport. * Explore the composition of blood, including red cells, white cells, and platelets. * Compare and contrast the open and closed circulatory systems found in different animal species. * Grasp the fundamental principles of blood pressure and systemic circulation. The course starts with essential terminology and the basic structure of circulatory systems. From there, you will read through detailed modules on the heart, blood vessels, and blood composition before exploring the diversity of circulation in the animal kingdom. This course is designed for absolute beginners. No prior background in biology is required to get started. Begin your journey into the fascinating world of cardiovascular biology today.
