Heart valve and strings, SEM
Heart valve and strings, coloured scanning electron micrograph (SEM). This is the mitral valve (upper right), controlling the blood flow between two of the hearts chambers, the left atrium (top) and the left ventricle (bottom). The heart strings (thread-like structures) are known as the chordae tendineae, and are controlled by the papilliary muscles (one at lower right). The structures at lower left, known as trabeculae carneae, are muscular, columnar protrusions found on the internal surface of the ventricles

EDITORS COMMENTS
This print showcases the intricate beauty of a heart valve and its surrounding structures. Taken using a scanning electron microscope (SEM), this colored image provides an up-close look at the mitral valve, which plays a crucial role in regulating blood flow between two chambers of the heart. The upper right corner reveals the mitral valve, responsible for controlling the passage of blood from the left atrium to the left ventricle. Delicate thread-like structures known as chordae tendineae extend from this valve, connecting it to papillary muscles located at the lower right. These muscles are responsible for controlling and adjusting tension on these heart strings. At lower left, we observe muscular columnar protrusions called trabeculae carneae that line the internal surface of the ventricles. These unique formations add strength to cardiac contractions while maintaining efficient blood circulation throughout our bodies. This stunning SEM image not only highlights these anatomical features but also emphasizes their importance within our circulatory system. It serves as a reminder of how seamlessly our cardiovascular system functions when all components work harmoniously together. With its vibrant colors and detailed textures, this print is an ideal addition for anyone interested in biology or cardiology. Its portrayal captures both scientific precision and aesthetic appeal, making it an excellent choice for those seeking to appreciate nature's wonders through artistry and science combined.
