False-colour SEM of a portion of a cardiac valve
Heart valve. False-colour scanning electron micrograph of a portion of one of the atrioventricular valves of the heart: either the tricuspid or the mitral valve. They channel the flow of blood from the atria to the ventricles and prevent any backflow. The image clearly shows the chordae tendineae, the fibrous filiform collagenous cords, which connect the cusps of the valve to the papillary muscles of the heart. The epithelium at top is known as the endocardium: it is formed by a single layer of flattened cells supported by fibro-elastic connective tissue. Magnification: x70 at 6x7cm size. x115 at 4x5ins

EDITORS COMMENTS
This print showcases a false-colour scanning electron micrograph of a portion of a cardiac valve. Specifically, it captures either the tricuspid or the mitral valve, which play a crucial role in directing blood flow from the atria to the ventricles while preventing any backflow. The intricate details are brought to life as we observe the chordae tendineae, fibrous filiform collagenous cords that connect the cusps of the valve to the papillary muscles of the heart. The top layer displayed in this image is known as endocardium, composed of flattened cells supported by fibro-elastic connective tissue. Its delicate structure highlights its importance in maintaining proper heart function. With an impressive magnification level of x70 at 6x7cm size and x115 at 4x5ins, this print allows us to appreciate every minute detail with awe-inspiring clarity. As we delve into this mesmerizing world within our own bodies, we gain a deeper understanding and appreciation for our remarkable anatomy. This print serves as a testament to both scientific exploration and artistic expression, capturing not only anatomical precision but also aesthetic beauty. Courtesy of Science Photo Library, this extraordinary piece invites us into an enchanting realm where science meets artistry – reminding us once again how truly fascinating and complex our human body is.
