cardiac cycle

The human circulatory system is a remarkable network that ensures the continuous flow of oxygen-rich and oxygen-depleted blood throughout our body. This intricate system, centered around the heart, plays a vital role in maintaining life by delivering essential nutrients and oxygen to every cell while removing waste products. The image illustrates the complex pathway of blood circulation, showing how blood moves between the heart, lungs, and various body parts.

The human heart functions as a sophisticated dual pump system, orchestrating the continuous flow of blood throughout the body. This detailed illustration demonstrates how blood circulates through the heart, lungs, and body in two distinct but interconnected circuits: the pulmonary circulation (between heart and lungs) and systemic circulation (between heart and rest of the body). The diagram uses color coding - red for oxygen-rich blood and blue for oxygen-poor blood - to clearly show the path of blood flow.

This detailed anatomical illustration presents a cross-sectional view of the human heart, highlighting its major chambers, valves, and blood vessels through a modern, clear design. The diagram effectively uses color coding to distinguish between oxygenated (red) and deoxygenated (blue) blood flow paths, making it an excellent educational resource for understanding cardiac anatomy.

The human heart stands as a remarkable organ that orchestrates the intricate dance of blood circulation throughout our bodies. This detailed anatomical diagram presents both external and internal views of the heart, showcasing the complex pathway of oxygenated and deoxygenated blood flow that sustains life.

The circulatory system is an essential network that facilitates blood flow throughout the body, consisting of two main circuits: pulmonary and systemic. This simplified diagram illustrates how blood moves through the heart chambers and major vessels, with blue representing deoxygenated blood and red showing oxygenated blood.

The human circulatory system is a remarkable network that connects the heart, lungs, and body tissues through an intricate system of blood vessels. This diagram illustrates how blood flows through both the pulmonary and systemic circuits, showing oxygen-rich and oxygen-poor blood pathways through different colored vessels - red for oxygen-rich and blue for oxygen-poor blood.

The human heart's blood flow system is a complex network that efficiently distributes oxygen and nutrients throughout the body. This educational illustration demonstrates how blood circulates through the heart, showing both oxygenated and deoxygenated blood flow patterns in a child-friendly format.

The circulatory system plays a vital role in maintaining life by circulating blood between the heart, lungs, and body tissues. This diagram illustrates the dual circulation pattern through pulmonary and systemic circuits, using blue to represent deoxygenated blood and red for oxygenated blood, demonstrating how oxygen-rich blood reaches all body parts while deoxygenated blood returns to the lungs for reoxygenation.
