Heart chambers and sinus node, artwork C014 / 2030
Heart chambers and sinus node (yellow). Cutaway artwork revealing the four internal heart chambers and the heart valves and tendons (white). The two upper chambers are the atria. The two bottom chambers are the ventricles. This view is from the front. Blood arrives in the right atrium (upper left), is passed to the right ventricle (lower left) and is pumped to the lungs. After oxygenation in the lungs, the blood arrives back in the left atrium (upper right) and passes to the left ventricle (lower right), which pumps it round the body. The sinus node (also sinoatrial node) generates the electrical impulse for each heartbeat

EDITORS COMMENTS
This artwork, titled "Heart Chambers and Sinus Node" offers a mesmerizing glimpse into the intricate workings of our cardiovascular system. Against a pristine white background, the illustration showcases the four internal heart chambers, heart valves, and tendons in striking detail. The vibrant yellow hue highlights the sinus node, also known as the sinoatrial node - an essential component responsible for generating electrical impulses that regulate each heartbeat. From this frontal perspective, we witness blood's remarkable journey through our circulatory system. It enters through the right atrium on the upper left side before passing to the right ventricle on its lower counterpart. From there, it is propelled towards our lungs for oxygenation. After this vital process occurs, oxygen-rich blood returns to us via the left atrium (upper right) and flows into the left ventricle (lower right), which then pumps it throughout our entire body. The artwork not only emphasizes key anatomical features but also underscores their significance in maintaining a healthy functioning organ. With precision and clarity, we observe how veins and arteries intertwine within this complex network while coronary arteries nourish cardiac tissue with life-sustaining nutrients. Claus Lunau's masterpiece serves as an educational tool that invites viewers to marvel at both artistry and biology simultaneously. Its meticulous attention to detail allows us to appreciate every aspect of our extraordinary cardiovascular system – from chambers and valves to tendons and impulses – reminding us of just how remarkable our bodies truly are.
