pulmonary circulation

Ventricular septal defect represents the most common congenital heart defect, affecting approximately 2-6 per 1000 live births. This condition involves an abnormal opening in the ventricular septum, allowing blood flow between the right and left ventricles, which can lead to significant hemodynamic consequences if left untreated.

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 heart is an extraordinary muscular organ that serves as the centerpiece of the human circulatory system. This detailed anatomical diagram showcases the intricate structures that make up the heart, including its chambers, valves, vessels, and muscular components. Each element plays a crucial role in maintaining the continuous flow of blood throughout the body, ensuring the delivery of oxygen and nutrients to every cell while removing waste products.

These detailed anatomical illustrations present both the external and internal views of the human heart, offering a unique comparative perspective of cardiac structure. The side-by-side diagrams demonstrate how the heart's external vessels and coronary circulation relate to its internal chambers and valves. This dual representation helps medical students, healthcare professionals, and interested learners understand the complex three-dimensional architecture of the heart.

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.

The heart serves as the body's primary circulatory pump, featuring four distinct chambers and multiple major blood vessels that work in perfect coordination. This anatomical illustration provides a clear view of the heart's main structures, using color coding to differentiate between oxygen-rich (red) and oxygen-poor (blue) blood flow paths, while also highlighting the crucial vessels that transport blood to and from the heart.

The circulatory system is a complex network that delivers oxygen, nutrients, and other essential substances throughout the body while removing waste products. This comprehensive diagram illustrates how blood flows through various organs and tissues, with red indicating oxygen-rich blood and blue showing oxygen-poor blood. The illustration demonstrates the intricate relationship between the heart, lungs, kidneys, and peripheral tissues in maintaining proper circulation.

The human circulatory system consists of two main circuits: the pulmonary and systemic circuits, working in harmony to maintain life. This detailed diagram illustrates how blood flows through these circuits, with blue indicating oxygen-poor blood and red showing oxygen-rich blood. The illustration effectively demonstrates the relationship between the heart, lungs, and body tissues in maintaining proper circulation and gas exchange.
