Arteries send blood away from the heart while veins send blood to the heart.
Arteries branch into smaller vessels called arterioles. Arterioles are small diameter blood vessels that connect arteries to capillaries. They play a crucial role in regulating blood flow and blood pressure within the circulatory system.
a vein could be considered a smaller artery, they are smaller and take blood to the heart and arteries take it to the heart.
The coronary arteries.
Coronary arteries branch from the aorta and supply the heart muscle.

The coronary arteries.
There are too many to count. There are also variations from person to person. The biggest arteries branch into smaller arteries and those branch into smaller and smaller arteries down to the arterioles, which are very small and there are many of them. Some people say there are millions of arteries in the human body. One source says there are so many arteries in the body that if you laid them end to end, they would be about 60,000 miles long.
Collaterals.
The blood pressure in the arteries will decrease as they move further away from the heart. The arteries are the vessels which regulate the blood pressure from the heart.Ê
The first vessels that branch off the aorta are called the coronary arteries. These arteries are so important for the heart muscle to work properly that they are the first off the aorta.These arteries give blood to the heart muscle itself. These arteries are also called coronary arteries because they form a crown around the top of the heart with the arteries forming an upside down crown.
The arteries are blood vessels that carry blood away from the heart to the rest of the body. Arteries branch into smaller arterioles, which branch into capillaries. Capillaries are one-cell thick and have a diameter of about the width of one blood cell. Capillaries form into venules, which form into veins, which carry blood to the heart from the rest of the body. Click on related links for an illustration.
Coronary arteries branch from the aorta and supply the heart muscle.
Arteries and veins both carry blood. Arteries are larger and carry blood away from the heart. Veins carry blood to the heart, and they are generally smaller than arteries.
The coronary arteries deliver blood to the muscles of the heart.
