Diagram showing blood flow of human heart illustration Stock Vector Biology Diagrams An average adult has 5 to 6 quarts (4.7 to 5.6 liters) of blood, which is made up of plasma, red blood cells, white blood cells and platelets. The heart is a muscular organ with four chambers.

In this video, we explore the anatomy of the human heart, detailing its chambers, valves, and the flow of blood through the cardiovascular system. Learn how

How Your Circulatory System Works Biology Diagrams
Learn how blood flows through your heart, lungs and body in a series of steps. See diagrams and explanations of the four chambers, valves and arteries of your heart.

They connect to smaller and smaller blood vessels as they get farther away from your heart to deliver oxygen and remove waste throughout your entire body. Blood vessels contain layers of connective tissue, muscle and elastic fibers. Muscles in your blood vessels control how wide they get, which also affects your blood pressure. The human circulatory system is an intricate network that extends throughout the entire body, carrying vital oxygen and nutrients to every cell. This comprehensive illustration combines a full-body view of the circulatory system with detailed heart anatomy, showing both external and internal perspectives of blood flow. The diagram uses blue to indicate deoxygenated blood vessels and red for The diagram presents a dual view: a full human body skeleton showing the location of vital organs, alongside a detailed representation of the cardiopulmonary system. The color-coded pathways clearly distinguish between oxygenated (red) and deoxygenated (blue) blood flow, making it easy to understand the complete circulation process.
