A collage of four images that show the different types of coronary arteries. The first image on the top left shows a close-up view of a coronary artery (clr) with a red and green color scheme. The artery appears to be elongated and has a curved shape. The red color is the dominant color in the image while the green color is a darker shade. In the top right image there is a closer view of the artery with a green and purple color scheme indicating that it is a normal artery. The image also shows a merged artery with red and yellow colors representing the blood vessels. The blood vessels are arranged in a circular pattern with the red blood vessels in the center and the yellow and purple blood vessels on either side. The merged arteries appear to be stained with a fluorescent dye which is a type of dye that helps to differentiate between the two types of arteries.
