Anatomical Heart Graphic Tee — Welsh Labeled Heart Diagram T-Shirt

This design is built as a clean two-part composition, with a small, simplified heart on the front and a much more detailed version on the back. The front keeps things minimal — a compact, colourful icon that works as a subtle chest print — while the back reveals the full illustration as a labelled anatomical diagram. The larger design shows the structure of the human heart, with key parts labelled in Welsh — including the atriwm dde/chwith (right/left atrium) and fentrigl dde/chwith (right/left ventricle). These four chambers work together to keep blood moving through the body, sending it to the lungs for oxygen and then back out to the rest of the body. It’s a nice balance of education and design. The labels add a bit of substance without overwhelming the illustration. Visually, everything is kept bold and graphic. The colours help distinguish oxygenated and deoxygenated blood, while the clean outlines and simple shapes keep it easy to read and visually striking from a distance. The contrast between the small front print and the detailed back design works really well — understated from the front, more expressive when you turn around. A clean, modern design that mixes science, language and graphic simplicity — a proper little anatomy lesson you can wear.
