The coronary veins drain into the coronary sinus, which is a collection of veins located on the posterior side of the heart. The coronary sinus then empties into the right atrium of the heart. This pathway allows for the deoxygenated blood from the heart muscle to return to the general circulation for reoxygenation. **

A diagram of coronary heart disease typically shows the narrowing or blockage of the coronary arteries, which supply blood to the heart muscle. The diagram may depict the build-up of plaque (made of cholesterol, calcium, and other substances) on the inner walls of the arteries, leading to reduced blood flow to the heart. It may also illustrate the potential formation of blood clots at the site of the plaque, which can further obstruct blood flow and lead to a heart attack. Additionally, the diagram may show the potential consequences of coronary heart disease, such as chest pain (angina), shortness of breath, and heart failure. **

The cause of a white coronary band and white hooves in horses is typically genetic. This condition is known as "white line disease" or "hoof wall separation disease" and is often seen in horses with white or light-colored hooves. It is believed to be caused by a lack of pigmentation in the hoof wall, which can make the hoof more susceptible to environmental factors such as moisture and bacteria. This can lead to separation of the hoof wall and the development of white lines or bands. Proper hoof care and regular trimming can help manage this condition. **
