Coronary arteries supply blood to the heart muscle Like all other tissues in the body, the heart muscle needs oxygenrich blood to function Also, oxygendepleted blood must be carried away The coronary arteries wrap around the outside of the heart Small branches dive into the heart muscle to bring it blood Lumen is large and floppy to allow easy flow of blood Which of the labeled layers in the diagram of the arterial wall is composed of a simple squamous epithelium, a basement membrane and a layer of Illustrations of the vein, artery, blood cells, heart and lymph node The difference of veins and arteries can be known when we see it LiningVeins contain valves, arteries don't;

Blood leaves the heart via the arteries, reaches the tissues via the capillaries, then returns to the heart via the veins Each blood vessel has a space through which the blood passes; Arteries are the blood vessels that carry blood away from the heart, where it branches into even smaller vessels Finally, the smallest arteries, called arterioles are further branched into small capillaries, where the exchange of all the nutrients, gases and other waste molecules are carried out Veins are the blood vessels present throughout the bodyA lumen in anatomy can also refer to an aperture or an opening within a fixed structure, such as the circular hole in a vertebral bone through which the spinal cord courses An aneurysm can increase in size until it blocks off the entire lumen of the vessel, or it ruptures One of the largest lumina in anatomy is the open space within the aorta

A Both arteries and veins have thick muscular walls to carry blood at high pressure B The majority of both arteries and veins contain valves to prevent the backflow of blood C Veins have a muscular wall to carry blood at high pressure, and arteries have valves to prevent the backflow of blood D Arteries have a muscular wall to carry blood at high pressure, and veins have valves toAnd are loosely classified as small, medium and large veins Another distinct feature of most veins (except the venae cavae, visceral organs and the central nervous system) is that they contain valves in the lumenCompared to arteries, veins are thinwalled vessels with large and irregular lumens (see Figure 16) Because they are lowpressure vessels, larger veins are commonly equipped with valves that promote the unidirectional flow of blood toward the heart and prevent backflow toward the capillaries caused by the inherent low blood pressure in
