larger blood vessels called veins which carry the blood back to the heart
Arterioles carry blood in the direction away from the heart. The order of vessels from the heart is: arteries>arterioles>capillaries>venules>veins.
Because the heart itself needs a blood supply in order to function. If the heart is starved of its own blood - it will stop.
your heart beats faster in order to supply more blood to the body

Heart (Left Ventricle) -> Arteries -> Arterioles -> Capillaries -> Venules -> Veins -> Heart (Right Atrium)
myocardium
Valves are primarily found in veins. They are important because when blood is returning to the heart from places like the feet, they are moving against gravity. In order to prevent the blood from falling down to the feet as it rises back to the heart, valves are in place in order to prevent the blood from flowing backward.
the blood passes through your heart
All the cell of your body are affected by heart disease. The cells of the body need the oxygen and nutrients carried by blood in order to survive. The heart pumps blood. If the heart is unable to adequately pump blood, the cells do not get what they need in order to survive, and will eventually die. Heart disease can be managed by your health care provider, and there are means to make the heart pump better in order to prolong the life of the cells that we need so much to survive.
The faster your heart beats the faster blood flows.
The coronary blood supply is the arteries which supply the heart itself; in order for the heart to function it needs a good supply of oxygen just the same as any other organ/muscle. Without the coronary blood supply the heart would not be able to pump blood around the body, a disruption in this blood supply would cause a heart attack.
