Blood vessels are one of the main parts of the circulatory system that helps in the transportation of blood in the entire body. These vessels plays an important role by transporting the essential components such as blood cells, flow of oxygen into the body tissues and other essential nutrients, and in return it eliminates CO₂ and other waste products from the body tissues.
These blood vessels are found in the bones of the organisms and are not found in the cartilages. This is how the blood vessels carries the valuable nutrients to different parts of the body through the bones.
